This horse hide strop was traditionally used to sharpen and polish straight edged razors, although it could be used for kitchen knives or chisels. The metal loop was designed to be hung onto a nail or peg, and the person held onto the handle and pull the strop taut. The razor was sharpened by drawing the spine down along the strop, so no pressure placed on the blade. Once the razor reached the bottom of the strop, it was flipped and drawn upwards. This process required skill, although it could be done at a great speed. Keen Kut was an American brand that sold razors, strops, and safety brands. Double sided, two strips. Metal ring one end, padded stitched handle at other. Horse hide.KEEN KUT /GENUINE HORSE HIDEchurchill island, strop, horse hide, tool, kleen kut
