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.
