[8] [9]) Alternatively, tungsten carbide blades can be used in knife sharpening. A clamp-on knife sharpener. The rod guides the sharpening stone to maintain a consistent angle. The angle can be adjusted by moving the guide posts up or down. This sharpener uses a diamond dust coated stone to remove metal from the knife blade.

View underneath a router table showing plunge router attached. A router may be mounted upside down in a router table or bench. The router's base plate is mounted to the underside of the table, with a hole allowing the bit to protrude above the table top. This allows the work to be passed over the router, rather than passing the router over the ...

The verb nowadays to describe the process of using a sharpening stone for a knife is simply to sharpen, but the older term to whet is still sometimes used, though so rare in this sense that it is no longer mentioned in, for example, the Oxford Living Dictionaries.
Sharpening these implements can be expressed as the creation of two intersecting planes which produce an edge that is sharp enough to cut through the target material. For example, the blade of a steel knife is ground to a bevel so that the two sides of the blade meet. This edge is then refined by honing until the blade is capable of cutting.
Router tables are used to increase the versatility of a hand-held router, as each method of use is particularly suited to specific application, e.g. very large workpieces would be too large to support on a router table and must be routed with a hand-held machine, very small workpieces would not support a hand-held router and must be routed on a ...

A variety of blade materials can be used to make the blade of a knife or other simple edged hand tool or weapon, such as a sickle, hatchet, or sword. The most common blade materials are carbon steel, stainless steel, tool steel, and alloy steel. Less common materials in blades include cobalt and titanium alloys, ceramic, obsidian, and plastic.
