A straight razor is a razor with a blade that can fold into its handle.[1] They are also called open razors and cut-throat razors.
HISTORY
The first modern straight razor complete with decorated handles and hollow ground blades was constructed in Sheffield, England, by Benjamin Huntsman in 1740. Huntsman's process was adopted by the French sometime later. The English manufacturers were even more reluctant than the French to adopt the process and only did so after they saw its success in France.[5] Straight razors were the most common form of shaving before the 20th century and remained that common in many countries until the 1950s.
TODAY
Straight razors are still manufactured. DOVO, of Solingen, Germany, and Thiers Issard of France are two of the most well-known European manufacturers. Feather Safety Razor Co. Ltd. of Osaka, Japan makes a razor with the same form as a traditional straight, but featuring a disposable blade that can be installed through an injector-type system.

Modern straight razor users are known to favor them for a variety of reasons. Some are attracted to the nostalgia of using old and traditional methods of shaving. It is a masculine ritual comparable to pipe smoking. Others profess an interest in reducing the waste of disposable blades.[11][22]

Still others agree that straight razors provide a superior shave through a larger blade and greater control of the blade including the blade angle. Straight razors cover a much greater area per shaving stroke because their cutting edge is much longer than any of the multiblade razors.

LONG EXTRACT FROM WIKI _ SHORTEN to describe 00121
The parts of a straight razor and their function are described as follows: The narrow end of the blade rotates on a pin called the pivot, between two protective pieces called the scales or handle. The upward curved metal end of the narrow part of the blade beyond the pivot is called the tang and acts as a lever to help raise the blade from the handle. One or two fingers resting on the tang also help stabilize the blade while shaving. The narrow support piece between the tang and the main blade is called the shank, but this reference is often avoided because it can be confusing. The shank sometimes features decorations and the stamp of the country of origin. The top side and the underside of the shank can sometimes exhibit indentations known as fluting, or jimps for a more secure grip.[8] The curved lower part of the main blade from the shank to the cutting edge is called the shoulder.[9] The point where the shoulder joins the cutting edge is called the heel.

A thick strip of metal running transversely at the junction where the main blade attaches to the shank is called the stabiliser. The stabiliser can be double,[10] single or can be absent in some razor models. The first stabiliser is usually very narrow and thicker and runs at the shank to blade junction, covering the shank and just spilling over to the shoulder. The second stabiliser can be distinguished since it is considerably wider and narrower, appearing after the first stabiliser and running lower into the shoulder.

The non-cutting top of the blade is called the back or the spine while the cutting part of the blade opposite the back is called the cutting edge.[11] Finally the other free end of the blade, at the opposite end of the tang, is called the point and, sometimes, the head or the nose.[9][12]

There are two to three pins in any handle. The middle pin, if present, is plastic coated and is called the plug.[13] Its function is to stabilise the sides of the handle so that they cannot be squeezed in the middle. When folded into the scales, the blade is protected from accidental damage, and the user is protected from accidental injury. During folding, the back of the blade, being thick and normally with a curved cross-section, acts as a natural stopper and prevents further rotation of the blade out of the handle from the other side
