Negative rake: A tool has a negative rake angle when the face of the cutting tool slopes away from the cutting edge at outer side. Positive rake angles generally: Make the tool more sharp and pointed. This reduces the strength of the tool, as the small included angle in the tip may cause it to chip away. Reduce cutting forces and power ...
The purpose of the sharpening jig is to hold the blade or tool at the desired angle while grinding or honing the bevel. In some cases, the angle of the bevel is critical to the performance of the cutting edge—a jig allows for repeatability of this angle over a number of sharpening sessions. There are many styles of jig available commercially.
In waterskiing, a bevel is the transition area between the side of the ski and the bottom of the ski. Beginners tend to prefer sharp bevels, which allow the ski to glide on the water surface.

A fillet knife has a bevel that is longer than other types of knives such as pocket, survival, or steak knives. The bevel is typically between 12 and 17 degrees to allow for a razor-sharp edge and a sharp point for puncturing. This bevel angle creates extreme sharpness but sacrifices durability. [6]
In practice, double bevels are common in a variety of edge angles and back bevel angles, and Western kitchen knives generally have a double bevel, with an edge angle of 14–16° (included angle of 28–32°) and a maximum of 40° as specified by International standard ISO 8442.1 (knives for the preparation of food).
