Kitchen Knives

Guidelines shown below are for Included Angles (⍺).

If you want to get truly sharp, Dr. Vadim Kraichuk with KnifeGrinders has a really good method and has adapted the Tormek system to these wheels. The KnifeGrinder method is one that is proven, and has great tools to assist with making it easy.

CB created an excellent USB Projection Calculator which can be used to calculate the settings you will need to use with the Tormek knife jigs. His calculations have been vetted for accuracy to the sub-degree level.
