Tool, Handshears
Hand shears needed to be very sharp and often had a leather strap or ‘driver’ which passed over the hand. Others had sheepskin bound around the grip. Blades had to be regularly sharpened on a grinding stone. Most hand shears were made in Sheffield, England, with various models produced offering wide or narrow blades, sharp or rounded points, and various grips and bows. The technique of Australian hand shearing gradually developed from the 1830s using the old English method of cutting the flank with hand shears in a series of circular cuts from the sheep’s neck to the tail. In the early 1930s the Ballarat School of Mines introduced a wide-ranging Wool Classing Course as jobs were in extremely short supply during the Great Depression.

Hacksaw Frame
A hacksaw is a fine-tooth saw with a blade held under tension by a frame. It is used for cutting materials such as metal or plastics. Hand-held hacksaws consist of a metal arch with a handle, usually a pistol grip, and pins for attaching a narrow disposable blade. A screw or other mechanism is used to put the thin blade under tension. The blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. On the push stroke, the arch flexes slightly, decreasing the tension on the blade.Steel frame for blade. adjustment lever in handle.Dimpled feature on curved sectionhacksaw, tool, ballarat school of mines, trade, cutting, metal, plastics -

Razor Strop
This razor strop is made like a leather strap. ABOUT STROPS Straight razors and cut throat razors were the major tools for shaving before the safety razor was invented in the 1880’s and even today specialty shaving shops still sell the straight razors. Along with the razor, the process of shaving would commonly involve lathering up shaving soap using a shaving brush with boar bristles. Men could own several razors and rotate them through the week and some shops sold the razors in a set, a razor for each day of the week. Straight razors could require stropping more than once during the shaving of a heavy beard, and stropping would also be performed at the end of each shave. Honing would only be performed two or three times a year, preserving the blade’s edge. A lot of skill was needed to hone and strop the blades of these early razors and the methods to do so were a large part of the curriculum in Barber colleges. The razor would be sharpened on a grinding wheel then honed on sharpening stone and finally finished using a strop. Straight edge razors would usually be sold unfinished and that process would be completed by the customer. A razor strop, usually made from leather, thick canvas or light timber, would be used to straighten and polish the straight razor for shaving. Strops could also be used to polish other blades such as knives, small metal tools and chisels. Sometimes an abrasive polishing compound is also used to give a mirror finish. Some strops, such as this one in our Collection, are designed to be used while hanging from a nail or peg, while others are hand held. To use the strop draw the spine of the blade down along the strop with the blade following, without putting any pressure on the blade. At the end of the stroke, rotate the blade over its spine then draw the spine along the strop again so that the edge moves away from the top. The finer grade of leather strap is used to give the final finish. Double Swing Razor Strop.

Tool - Wood Saw, Mid to late 20th century
A saw is a tool consisting of a tough blade, wire, or chain with a hard-toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. The cut is made by placing the toothed edge against the material and moving it forcefully forth and less vigorously back or continuously forward. This force may be applied by hand, or powered by steam, water, electricity or other power sources. An abrasive saw has a powered circular blade designed to cut through metal or ceramic. In ancient Egypt, open (unframed) saws made of copper are documented as early as the Early Dynastic Period, circa 3,100–2,686 BC. Many copper saws were found in tombs dating to the 31st century BC. Models of saws have been found in many contexts throughout Egyptian history. As the saw developed, teeth were raked to cut only on the pull stroke and set with the teeth projecting only on one side, rather than in the modern fashion with an alternating set. Saws were also made of bronze and later iron. In the Iron Age, frame saws were developed holding the thin blades in tension. The earliest known sawmill is the Roman Hierapolis sawmill from the third century AD used for cutting stone. The subject item at this time cannot be associated with an historical event, person or place, provenance is unknown, as the maker is unknown but the pattern or design and type of wood used indicate it is a tool of modern manufacture around the mid to late 20th century.Wood hand saw with wooden handle attached to saw by 4 rivets.

The Process of Making Pottery Decorating, Firing, Glazing, Making, Technical There is a rhythm and flow to clay. It can’t be done all at once! Even the making process! It can take weeks to get everything done, especially if you can only work on your pottery once a week! Even though we have three hour classes, it’s often just not enough time! Here is an overview of some of the processes so you have a bit more grasp on some of the technical stuff! Step One – Design There are SO many ideas out there for making stuff in clay! From delicate porcelain jewellery, through to heavy sculptural work and everything in between. Deciding your direction is sometimes not that easy – when you first start, try everything, you will naturally gravitate to the style that you enjoy! The options and variations are endless and can get a wee bit overwhelming too! Check in with me before you start to ensure your ideas will work, what order you might do things, how you could achieve the look you are seeking and any other technical data required! Step Two – Making Clay is thixotropic. This means that as you work with it, the clay first gets sloppier and wetter, before is begins to dry in the atmosphere. For most things, you simply can’t do all parts of the project at once. An example of work order might look like: Get last weeks work out from the shelves Prepare clay for today’s work – roll your clay, prepare balls for throwing, make the first stage of a pinch pot) Clean up last week’s work and put it on the shelf for bisque firing Check that you have any glazing to do – and do enough of it that you will have time to finish your main project Do the next step of your next project – there might be a further step that can’t be complete immediately, in that case, wrap your work well and put onto the shelves. Letting your work rest for a while can really help keep your work clean and professional looking. Many things require bagging under plastic to keep it ready for work the next week – put your name on the outside of the bag so you can find your work easily. We have stickers and markers. Consider how you want to decorate your work – coloured slip can be applied at a fairly wet stage (remembering that it will make your work even wetter!). Trying to apply slip to dry clay won’t work! If you want to do sgraffito – you will need to keep the work leather hard (a state of dryness where you can still work the clay with a little effort and a little water and care). Step Three – Drying Most of the time your work can go into the rack uncovered to let it dry out for the following week. If you want to continue forming or shaping you will need to double bag your work – put your work on a suitable sized bat and put the bat in a bag so the base of the bag is under the bat, then put another bag over the top of the work and tuck the top of the bag under the bat. If you want to trim (or turn) your thrown work the following week, it should also be double bagged. If your work is large, delicate, or of uneven thicknesses, you should lightly cover your work for drying. When considering the drying process, bare in mind the weather, humidity and wind! The hotter and dryer, the faster things dry and work can dry unevenly in the shelves – this can lead to cracking – another time to lightly cover your work for drying. Step Four – Trimming and Cleaning Up Your work is dry! It is called greenware now and it is at it’s most fragile! Handle everything with two hands. I often refer to soft hands – keep everything gentle and with your fingers spread as much as possible. Try to not pick up things like plates too much, and always with both hands! Before your work can be bisque fired it should be “cleaned up”. You work won’t go into the kiln if it has sharp edges – when glazed, sharp edges turn into razor blades! Use a piece of fly wire to rub the work all over – this will scratch a little so be light handed. Use a knife or metal kidney to scrape any areas that require a bit more dynamic treatment than the fly wire offers! Finally, a very light wipe over with a slightly damp sponge can help soften and soothe all of your edges and dags! Trimming thrown work: If you are planning to trim (or turn) your thrown work (and you should be), make sure you bag it well – your work should be leather hard to almost dry for easiest trimming. Use this step to finish the work completely – use a metal kidney to polish the surface, or a slightly damp sponge to give a freshly thrown look. Wipe the sponge around the rim after trimming, and check the inside of the pot for dags! Trimming slip cast work: Usually I will trim the rims of your work on the wheel the following day to make that stage easier, however you will still need to check your work for lumps and bumps. Last but not least – check that your name is still clearly on the bottom of your work. Step Five – Bisque Firing When the work is completely dry it can go into the bisque kiln. The bisque kiln is fired to 1000°C. This process burns off the water in the clay as well as some of the chemically bound water. The structure of the clay is not altered that much at this temperature. Inside the bisque kiln, the work is stacked a little, small bowl inside a larger bowl and onto a heavy plate. Smaller items like decorations or drink coasters might get stacked several high. Consideration is paid to the weight of the stack and shape of the work. A bisque kiln can fire about one and a half times the amount of work that the glaze kiln can fire. The firing takes about 10 hours to complete the cycle and about two days to cool down. Once it has been emptied the work is placed in the glaze room ready for you to decorate! Step Six – Glazing Decorating your work with colour can be a lot of fun – and time consuming! There are three main options for surface treatment at this stage: Oxide Washes Underglazes Glazes Washes and underglazes do not “glaze” the work – It will still need a layer of glaze to fully seal the clay (washes don’t need glaze on surfaces not designed for food or liquid as they can gloss up a little on their own). Underglazes are stable colourants that turn out pretty much how they look in the jar. They can be mixed with each other to form other colours and can be used like water colours to paint onto your work. Mostly they should have a clear glaze on top to seal them. Oxides are a different species – the pink oxide (cobalt) wash turns out bright blue for instance. They don’t always need a glaze on top, and some glazes can change the colour of the wash! The glazes need no other “glaze” on top! Be careful of unknown glaze interactions – you can put any combination of glaze in a bowl or on a plate, but only a single glaze on the outside of any vertical surface! Glazes are a chemical reaction under heat. We don’t know the exact chemicals in the Mayco glazes we use. I can guess by the way they interact with each other, however, on the whole, you need to test every idea you have, and not run the test on a vertical surface! Simply put, glaze is a layer of glass like substance that bonds with the clay underneath. Clay is made of silica, alumina and water. Glaze is made of mostly silica. Silica has a melting point of 1700°C and we fire to 1240°C. The silica requires a “flux” to help it melt at the lower temperature. Fluxes can be all sorts of chemicals – a common one is calcium – calcium has a melting point of 2500°C, however, together they both melt at a much lower temperature! Colourants are metal oxides like cobalt (blue), chrome (green through black), copper (green, blue, even red!), manganese (black, purple and pink) iron (red brown), etc. Different chemicals in the glaze can have dramatic effects. for example, barium carbonate (which we don’t use) turns manganese bright pink! Other elements can turn manganese dioxide brown, blue, purple and reddish brown. Manganese dioxide is a flux in and of itself as well. So, glazes that get their black and purple colours, often interact with other glazes and RUN! Our mirror black is a good example – it mixes really well with many glazes because it fluxes them – causes them to melt faster. It will also bring out many beautiful colours in the glazes because it’s black colouring most definitely comes from manganese dioxide! Glaze chemistry is a whole subject on it’s own! We use commercial Mayco glazes on purpose – for their huge range of colour possibilities, stability, cool interactions, artistic freedom with the ability to easily brush the glazes on and ease of use. We currently have almost 50 glazes on hand! A major project is to test the interactions of all glazes with each other. That is 2,500 test tiles!!!! I’m going to make the wall behind the wheels the feature wall of pretty colours! Step Seven – Glaze (Gloss or sometimes called “Glost”) Firing Most of the time this is the final stage of making your creation (but not always!) The glaze kiln goes to 1240°C. This is called cone 6, or midrange. It is the low end of stoneware temperatures. Stoneware clays and glazes are typically fired at cone 8 – 10, that is 1260 – 1290°C. The energy requirement to go from 1240°C to 1280°C is almost a 30% more! Our clay is formulated to vitrify (mature, turn “glass-like”) at 1240°, as are our glazes. A glaze kiln take around 12 hours to reach temperature and two to three days to cool down. Sometimes a third firing process is required – this is for decoration that is added to work after the glaze firing. For example – adding precious metals and lustres. this firing temperature is usually around 600 – 800°C depending upon the techniques being used. There are many students interested in gold and silver trims – we will be doing this third type of firing soon! After firing your work will be in the student finished work shelves. Remember to pay for it before you head out the door! There is a small extra charge for using porcelain clay (it’s more than twice the price of regular clay), and for any third firing process! Once your work has been fired it can not turn back into clay for millennia – so don’t fire it if you don’t like it! Put it in the bucket for recycling. https://firebirdstudios.com.au/the-process-of-making-pottery/Ceramics have evolved over thousands of years.White earthenware dinner plate.

Inside the bisque kiln, the work is stacked a little, small bowl inside a larger bowl and onto a heavy plate. Smaller items like decorations or drink coasters might get stacked several high. Consideration is paid to the weight of the stack and shape of the work. A bisque kiln can fire about one and a half times the amount of work that the glaze kiln can fire. The firing takes about 10 hours to complete the cycle and about two days to cool down. Once it has been emptied the work is placed in the glaze room ready for you to decorate! Step Six – Glazing Decorating your work with colour can be a lot of fun – and time consuming! There are three main options for surface treatment at this stage: Oxide Washes Underglazes Glazes Washes and underglazes do not “glaze” the work – It will still need a layer of glaze to fully seal the clay (washes don’t need glaze on surfaces not designed for food or liquid as they can gloss up a little on their own). Underglazes are stable colourants that turn out pretty much how they look in the jar. They can be mixed with each other to form other colours and can be used like water colours to paint onto your work. Mostly they should have a clear glaze on top to seal them. Oxides are a different species – the pink oxide (cobalt) wash turns out bright blue for instance. They don’t always need a glaze on top, and some glazes can change the colour of the wash! The glazes need no other “glaze” on top! Be careful of unknown glaze interactions – you can put any combination of glaze in a bowl or on a plate, but only a single glaze on the outside of any vertical surface! Glazes are a chemical reaction under heat. We don’t know the exact chemicals in the Mayco glazes we use. I can guess by the way they interact with each other, however, on the whole, you need to test every idea you have, and not run the test on a vertical surface! Simply put, glaze is a layer of glass like substance that bonds with the clay underneath. Clay is made of silica, alumina and water. Glaze is made of mostly silica. Silica has a melting point of 1700°C and we fire to 1240°C. The silica requires a “flux” to help it melt at the lower temperature. Fluxes can be all sorts of chemicals – a common one is calcium – calcium has a melting point of 2500°C, however, together they both melt at a much lower temperature! Colourants are metal oxides like cobalt (blue), chrome (green through black), copper (green, blue, even red!), manganese (black, purple and pink) iron (red brown), etc. Different chemicals in the glaze can have dramatic effects. for example, barium carbonate (which we don’t use) turns manganese bright pink! Other elements can turn manganese dioxide brown, blue, purple and reddish brown. Manganese dioxide is a flux in and of itself as well. So, glazes that get their black and purple colours, often interact with other glazes and RUN! Our mirror black is a good example – it mixes really well with many glazes because it fluxes them – causes them to melt faster. It will also bring out many beautiful colours in the glazes because it’s black colouring most definitely comes from manganese dioxide! Glaze chemistry is a whole subject on it’s own! We use commercial Mayco glazes on purpose – for their huge range of colour possibilities, stability, cool interactions, artistic freedom with the ability to easily brush the glazes on and ease of use. We currently have almost 50 glazes on hand! A major project is to test the interactions of all glazes with each other. That is 2,500 test tiles!!!! I’m going to make the wall behind the wheels the feature wall of pretty colours! Step Seven – Glaze (Gloss or sometimes called “Glost”) Firing Most of the time this is the final stage of making your creation (but not always!) The glaze kiln goes to 1240°C. This is called cone 6, or midrange. It is the low end of stoneware temperatures. Stoneware clays and glazes are typically fired at cone 8 – 10, that is 1260 – 1290°C. The energy requirement to go from 1240°C to 1280°C is almost a 30% more! Our clay is formulated to vitrify (mature, turn “glass-like”) at 1240°, as are our glazes. A glaze kiln take around 12 hours to reach temperature and two to three days to cool down. Sometimes a third firing process is required – this is for decoration that is added to work after the glaze firing. For example – adding precious metals and lustres. this firing temperature is usually around 600 – 800°C depending upon the techniques being used. There are many students interested in gold and silver trims – we will be doing this third type of firing soon! After firing your work will be in the student finished work shelves. Remember to pay for it before you head out the door! There is a small extra charge for using porcelain clay (it’s more than twice the price of regular clay), and for any third firing process! Once your work has been fired it can not turn back into clay for millennia – so don’t fire it if you don’t like it! Put it in the bucket for recycling. https://firebirdstudios.com.au/the-process-of-making-pottery/Ceramics have evolved over thousands of years.A white earthenware side plate with a gadroon edge.

The Process of Making Pottery Decorating, Firing, Glazing, Making, Technical There is a rhythm and flow to clay. It can’t be done all at once! Even the making process! It can take weeks to get everything done, especially if you can only work on your pottery once a week! Even though we have three hour classes, it’s often just not enough time! Here is an overview of some of the processes so you have a bit more grasp on some of the technical stuff! Step One – Design There are SO many ideas out there for making stuff in clay! From delicate porcelain jewellery, through to heavy sculptural work and everything in between. Deciding your direction is sometimes not that easy – when you first start, try everything, you will naturally gravitate to the style that you enjoy! The options and variations are endless and can get a wee bit overwhelming too! Check in with me before you start to ensure your ideas will work, what order you might do things, how you could achieve the look you are seeking and any other technical data required! Step Two – Making Clay is thixotropic. This means that as you work with it, the clay first gets sloppier and wetter, before is begins to dry in the atmosphere. For most things, you simply can’t do all parts of the project at once. An example of work order might look like: Get last weeks work out from the shelves Prepare clay for today’s work – roll your clay, prepare balls for throwing, make the first stage of a pinch pot) Clean up last week’s work and put it on the shelf for bisque firing Check that you have any glazing to do – and do enough of it that you will have time to finish your main project Do the next step of your next project – there might be a further step that can’t be complete immediately, in that case, wrap your work well and put onto the shelves. Letting your work rest for a while can really help keep your work clean and professional looking. Many things require bagging under plastic to keep it ready for work the next week – put your name on the outside of the bag so you can find your work easily. We have stickers and markers. Consider how you want to decorate your work – coloured slip can be applied at a fairly wet stage (remembering that it will make your work even wetter!). Trying to apply slip to dry clay won’t work! If you want to do sgraffito – you will need to keep the work leather hard (a state of dryness where you can still work the clay with a little effort and a little water and care). Step Three – Drying Most of the time your work can go into the rack uncovered to let it dry out for the following week. If you want to continue forming or shaping you will need to double bag your work – put your work on a suitable sized bat and put the bat in a bag so the base of the bag is under the bat, then put another bag over the top of the work and tuck the top of the bag under the bat. If you want to trim (or turn) your thrown work the following week, it should also be double bagged. If your work is large, delicate, or of uneven thicknesses, you should lightly cover your work for drying. When considering the drying process, bare in mind the weather, humidity and wind! The hotter and dryer, the faster things dry and work can dry unevenly in the shelves – this can lead to cracking – another time to lightly cover your work for drying. Step Four – Trimming and Cleaning Up Your work is dry! It is called greenware now and it is at it’s most fragile! Handle everything with two hands. I often refer to soft hands – keep everything gentle and with your fingers spread as much as possible. Try to not pick up things like plates too much, and always with both hands! Before your work can be bisque fired it should be “cleaned up”. You work won’t go into the kiln if it has sharp edges – when glazed, sharp edges turn into razor blades! Use a piece of fly wire to rub the work all over – this will scratch a little so be light handed. Use a knife or metal kidney to scrape any areas that require a bit more dynamic treatment than the fly wire offers! Finally, a very light wipe over with a slightly damp sponge can help soften and soothe all of your edges and dags! Trimming thrown work: If you are planning to trim (or turn) your thrown work (and you should be), make sure you bag it well – your work should be leather hard to almost dry for easiest trimming. Use this step to finish the work completely – use a metal kidney to polish the surface, or a slightly damp sponge to give a freshly thrown look. Wipe the sponge around the rim after trimming, and check the inside of the pot for dags! Trimming slip cast work: Usually I will trim the rims of your work on the wheel the following day to make that stage easier, however you will still need to check your work for lumps and bumps. Last but not least – check that your name is still clearly on the bottom of your work. Step Five – Bisque Firing When the work is completely dry it can go into the bisque kiln. The bisque kiln is fired to 1000°C. This process burns off the water in the clay as well as some of the chemically bound water. The structure of the clay is not altered that much at this temperature.

When the ship Schomberg was launched in 1855, she was considered the most perfect clipper ship ever to be built. James Blaine’s Black Ball Line had commissioned her to be built for their fleet of passenger liners. At a cost of £43,103, the Aberdeen builders designed her to sail faster than the quick clippers designed by North American Donald McKay. She was a three masted wooden clipper ship, built with diagonal planking of British oat with layers of Scottish larch. This luxury vessel was designed to transport emigrants to Melbourne in superior comfort. She had ventilation ducts to provide air to the lower decks and a dining saloon, smoking room, library and bathrooms for the first class passengers. At the launch of Schomberg’s maiden voyage, her master Captain ‘Bully’ Forbes, drunkenly predicted that he would make the journey between Liverpool and Melbourne in 60 days. Schomberg departed Liverpool on 6 October 1855 with 430 passengers and 3000 tons cargo including iron rails and equipment intended the build the Geelong Railway and a bridge over the Yarra from Melbourne to Hawthorn. The winds were poor as Schomberg sailed across the equator, slowing her journey considerably. She was 78 days out of Liverpool when she ran aground on a sand-spit near Peterborough, Victoria, on 27 December; the sand spit and the currents were not marked on Forbes’s map. Overnight, the crew launched a lifeboat to find a safe place to land the ship’s passengers. The scouting party returned to Schomberg and advised Forbes that it was best to wait until morning because the rough seas could easily overturn the small lifeboats. The ship’s Chief Officer spotted SS Queen at dawn and signalled the steamer. The master of the SS Queen approached the stranded vessel and all of Schomberg’s passengers were able to disembark safely. The Black Ball Line’s Melbourne agent sent a steamer to retrieve the passengers’ baggage from the Schomberg. Other steamers helped unload her cargo until the weather changed and prevented the salvage teams from accessing the ship. Local merchants Manifold & Bostock bought the wreck and cargo, but did not attempt to salvage the cargo still on board the ship. They eventually sold it on to a Melbourne businessman and two seafarers. After two of the men drowned when they tried to reach Schomberg, salvage efforts were abandoned.32 In 1975, divers from Flagstaff Hill, including Peter Ronald, found an ornate communion set at the wreck. The set comprised a jug, two chalices, a plate and a lid. The lid did not fit any of the other objects and in 1978 a piece of the lid broke off, revealing a glint of gold. As museum staff carefully examined the lid and removed marine growth, they found a diamond ring, which is currently on display in the Great Circle Gallery.33 Flagstaff Hill also holds ship fittings and equipment, personal effects, a lithograph, tickets and photograph from the Schomberg. Most of the artefacts were salvaged from the wreck by Peter Ronald, former director of Flagstaff Hill. The Schomberg, which is on the Victorian Heritage Register (VHR S612), has great historical significance as a rare example of a large, fast clipper ship on the England to Australia run, carrying emigrants at the time of the Victorian gold rush. She represents the technical advances made to break sailing records between Europe and Australia. Flagstaff Hill’s collection of artefacts from the Schomberg is significant for its association with the shipwreck. The collection is primarily significant because of the relationship between the objects, as together they have a high potential to interpret the story of the Schomberg. It is archaeologically significant as the remains of an international passenger Ship. It is historically significant for representing aspects of Victoria’s shipping history and for its association with the shipwreck and the ship, which was designed to be fastest and most luxurious of its day Part of a Pocket knife handle, wooden handle with metal inlay on one side, blade missing.

The set comprised a jug, two chalices, a plate and a lid. The lid did not fit any of the other objects and in 1978 a piece of the lid broke off, revealing a glint of gold. As museum staff carefully examined the lid and removed marine growth, they found a diamond ring, which is currently on display in the Great Circle Gallery.33 Flagstaff Hill also holds ship fittings and equipment, personal effects, a lithograph, tickets and photograph from the Schomberg. Most of the artefacts were salvaged from the wreck by Peter Ronald, former director of Flagstaff Hill. The Schomberg, which is on the Victorian Heritage Register (VHR S612), has great historical significance as a rare example of a large, fast clipper ship on the England to Australia run, carrying emigrants at the time of the Victorian gold rush. She represents the technical advances made to break sailing records between Europe and Australia. Flagstaff Hill’s collection of artefacts from the Schomberg is significant for its association with the shipwreck. The collection is primarily significant because of the relationship between the objects, as together they have a high potential to interpret the story of the Schomberg. It is archaeologically significant as the remains of an international passenger Ship. It is historically significant for representing aspects of Victoria’s shipping history and for its association with the shipwreck and the ship, which was designed to be fastest and most luxurious of its day Piece of metal pocket knife, with an end section and blade with broken end.

Manufactured Object, stainless steel razor blade holder, c1950
... razor blade holder Metal manufacturer ...King Camp Gillette observed in 1902 that as existing, relatively expensive, razor blades dulled quickly and needed continuous sharpening, a razor whose blade could be thrown away when it dulled would meet a real need and likely be profitable. Gillette's innovation was the thin, inexpensive, disposable blade of stamped steel. Safety razors had been developed in the mid-19th century, but still used a forged blade that dulled and rusted.. Gillette's safety razor was expensive but lasted many years and the convenience of inexpensive disposable sharp blades was very profitable for Gillette.Throughout the 20thC most men used a safety razor with disposable stainless steel razor blades to shave their beards prior to the introduction of affordable electric razors in 1960's.A two piece stainless steel razor blade holder. The base has a round hole to safely push blade with fingertip and the lid has side finger grooves to aid opening.

Tools, metal scythe, c1880
A scythe is an agricultural hand tool for mowing grass or reaping crops. It was largely replaced by horse-drawn and then tractor machinery. A scythe consists of a wooden shaft and a long, curved blade is mounted at the lower end, perpendicular. Scythes always have the blade projecting from the left side when in use. Mowing is done by holding the handle , with the arms straight, the blade parallel to the ground and very close to it, and the body twisted to the right. The body is then twisted steadily to the left, moving the scythe blade along its length in a long arc from right to left, ending in front of the mower, thus depositing the cut grass to the left. Mowing proceeds with a steady rhythm, stopping at frequent intervals to sharpen the blade. The correct technique has a slicing action on the grass, cutting a narrow strip with each stroke Mowing grass is easier when it is damp, and so hay-making traditionally began at dawn and often stopped early, the heat of the day being spent raking and carting the hay cut on previous daysEarly settlers and market gardeners used these scythes as they established their farms in Moorabbin Shire c1880A large metal scythe with a wooden handle x 2early settlers, pioneers, market gardeners, moorabbin, bentleigh, brighton, cheltenham, tools, blacksmiths
