Guidelines shown below are for Included Angles ().
The shape of the grind used is a call best made by the tool's use, based on your own experience. Additional notes are available for Grind Profiles.
I've not found value in adding micro/secondary bevels to pocket knives which get used, so that is not recommended here. If the sharpener wants to add one, an additional 2° should be sufficient. (More notes are also available on a different web page for Micro / Secondary Bevels.)
CB's USB Projection Calculator is recommended for calculating setup for Tormek knife jigs. (The simpler Projection Calculator is also still available.)
Drop Point Blade
This is a common blade and is sharpened to an angle which is good when a sharp tool is needed.
When sharpening a Swiss Army Knife (or knives with similar blades), no micro-bevel is added. This is due to the blade's overall thickness being thinner.
||This is a blade often used for scraping actions. Thusly, it is sharpened to a greater angle, and no secondary grind is applied.|
Sheep's Foot Blade
This blade is sharpened to a greater angle. This is to allow for its use on tougher materials.
(This is sometimes called a "Spey Point Blade".)
