Guidelines shown below are for Included Angles (⍺).

Notes about Secondary Bevels are at the bottom of this page.

Sharpening axes on the Tormek uses the Tormek SVA-170 Axe Jig. Alternatively, an angle grinder can be used with a 120 grit flap disc.

General Guidelines
Axe Type Included Angle (⍺) Secondary Bevel Notes
General 20-25º +2-5º This is a guideline. Exact angles are not required.

There are some who recommend that the overall grind be convex (see also, the referenced manual at the bottom of this page from the U.S. Dept. of Agriculture's Forest Service). I have found that using a secondary bevel removes that need.

Carpenter 20-25º +2-5º Grind the edge so there is a longer side facing the wood.
Felling 30-35º +2-5º
Hunting 30-35º +2-5º
