Sharpening stones (Water stones or Whetstones) are used to sharpen the edges of steel tools and implements through grinding and honing. Though "whetstone is often mistaken as a reference to the water sometimes used to lubricate such stones, the term is based on the word "whet", which means to sharpen a blade, not on the word "wet".
Sharpening stones come in a wide range of shapes, sizes and material compositions. Stone may be flat for working flat edges or shaped for more complex edges. It may be natural or artificial stones. Artificial stones usually come in the form of a bonded abrasive composed of a ceramic such as silicon carbide (carborundum) or of aluminium oxide (corundum). Bonded abrasives provide a faster cutting action than natural stones. They are commomly available as a double-sided block with a coarse grit on one side and a fine grit on the other enabling one stone to satisfy the basic requirements of sharpening. Natural stones are typically formed of quartz, such as novaculite.
Stones are usually available in various grades, which prefer to the grit size of the abrasive particles in the stone. Grit size is given as a number, which indicates the spatial density of the particles. A higher number denotes a higher density and therefore smaller particles, which leads to a finer finish of the surface of the polished object.
When the block is intended for installation on a bench it is called a bench stone. Small, portable stones are called pocket stones. Being smaller, they are more portable than bench stone but present difficulty in maintaining a consistent angle and pressure when drawing the stone along larger blades. However, they still can form a good edge. Frequently, fine grained pocket stones are used for honing, especially "in the field".
