Chisel
A chisel is a tool with a characteristically shaped cutting edge of blade on its end, for carving or cutting a hard material such as wood, stone, or metal. The handle and blade of some types of chisel are made of metal or wood with a sharp edge in it.In use, the chisel is forced into the material...

Sharpening is the process of creating or refining a sharp edge of appropriate shape on a tool or implement designed for cutting. Sharpening is done by grinding away material on the implement with an abrasive substance harder than the material of the implement, followed sometimes by processes to...

Sharpening stones, water stones or whetstones are used to grind and hone the edges of steel tools and implements. Examples of items that may be sharpened with a sharpening stone include scissors, scythes, knives, razors and tools such as chisels, hand scrapers and plane blades...
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.
