Superfinishing, also known as microfinishing [1] and short-stroke honing, is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer of fragmented or smeared metal left by the last process with an abrasive stone or tape; this layer is usually about 1 μm in magnitude.
The type of core that can be used depends on the type of materials that the diamond blade is designed to cut. Generally, there are three types of sintered metal-bonded diamond blades according to their manufacturing methods: wholly sintered diamond blades, silver brazed diamond blades and laser welded diamond blades.
On high quality blades, only the back of the blade and the adjacent sides (called the shinogi-ji), are polished to a mirror-like surface. To bring out the grain and hamon, the center portion of the blade (called the hira), and the edge (the ha), are usually given a matte finish. Microscopic scratches in the surface vary, depending on hardness.
Diamond stones can be useful in the sharpening process. Diamond is the hardest naturally occurring substance known and as such can be used to sharpen almost any material. [9] (Coarse diamond sharpening stones can be used for flattening waterstones. [9] [10]) Alternatively, tungsten carbide blades can be used in knife sharpening.

A channel setting is a method whereby stones are suspended between two bars or strips of metal, called channels. Typically, a line of small stones set between two bars is called a channel setting, and a design where the bars cross the stones is called a bar set. The channel is a variation of a "U" shape, with two sides and a bottom.
