Kitchen Knives

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 kitchen knives, so that is not recommended here. If the sharpener wants to add one, an additional 2° should be sufficient. (Additional 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. This one is web-based and does not require Excel.)

General Guidelines
Type Notes
Bread Knife (use these instructions : Serrated Edge Knives)
Butcher Knife 40°
Chopping Knife 30°
Clever 50°
Filleting Knife 15°
General Knife 24°
Could be anything up to 35°, however Dr. Vadim Kraichuk at KnifeGrinders recommends 24°. Given his vast experience and testing data, this is the recommended value.
Paring Knife 24°
Single Bevel 16°
This is for quality, high-carbon knives. For lesser quality knives, consider increasing to 20°. KnifeGrinders have documented the procedure they use, and also created a YouTube video.

Jigs, Fixtures, & Modifications. Jan Švancara posted a design for using a knife sharpening platform in 2015 on the Tormek Forum. This is certainly worth reading, and there are also pictures of this in the jigs section.
