 removes metal bent out of alignment from the blade's edge, stropping the blade re-aligns the indentations without removing any material.

The strop may be a hanging strop or a hand-held paddle. Various abrasive compounds may be applied to the strop to aid in polishing the blade while stropping to obtain a mirror-like finish. The properties of the compound applied will alter the polishing result. Jeweler's rouge is a very fine abrasive compound. The green Chromium(III) oxide

, as these are the thinnest blades in everyday use, and require stropping at each use, due to the thinness of the blade. Kitchen knives are instead straightened on a honing steel, which is coarser. Any blade may in principle be stropped to polish it.

Method

Two points are key to stropping:
  • Draw the blade spine-first along the strop. By contrast, honing is done edge-first.
  • Rotate the blade along the spine, so the edge moves away from the strop and faces you, and the spine rests on the strop. This preserves the edge – if the blade is rotated on the edge (facing away from you), this will roll the blade, defeating the purpose of stropping.
