Guidelines shown below are for Included Angles (⍺).
Notes are also available on a different web page for Micro / Secondary Bevels.
Sharpening axes on the Tormek uses the Tormek SVA-170 Ax Jig. Alternatively, an angle grinder can be used with a 120 grit flap disc.
There are some who recommend that the overall grind be convex (see also, An Ax to Grind: A Practical Ax Manual from the U.S. Forest Service). I have found that using a secondary bevel removes that need.
|Ax Type||α||Secondary Bevel||Notes|
|Soft Wood||Hard Wood|
|General||20º||25º||2º - 5º||This is a guideline. Exact angles are not required.|
|Carpenter||20º||25º||Grind the edge so there is a longer side facing the wood.|
Also, this position sharpens faster.
