Razor strop
(重定向自Razor strap)
A razor strop (or razor strap) is a flexible strip of leather or canvas used to straighten and polish the blade of a straight razor, a knife, or a woodworking tool like a chisel. Unlike honing or sharpening a blade, in which a whetstone removes metal bent out of alignment from the blade's edge, stropping the blade re-aligns the indentations without removing any material.
