Leather Strop

A leather strop is a tool used in sharpening blades. It helps even out any tiny burrs on the blade edge, making it smooth and sharp. When blades get dull, it is generally due to tiny degradations in quality from the sharpened blade. These can include small nicks and burrs on the cutting edge.

When blades are sharpened, they are usually done so by going over the edge with increasingly fine-grained stones or sharpeners. Coarser sharpening stones are used first to even out larger burrs. Then finer stones to reduce smaller burrs. Once the leather strop is used, it’s usually the last and finest-grained tool in the sharpening lineup.
