Rotary Cutters

Wheels on Rotary Cutters are sharpened according to the angles shown below. The calculation of ⍺ is measured according to the drawing to the right.

These are sharpened using the SVD-186 or SVD-185 jig, but with the thumb nut replaced by a hand wheel.

General Guidelines
This is a best estimate; it is best to match the existing edge if possible.

For the final sharpening, I've found it best to use the Tormek SJ-250 wheel, and use this for sharpening the cutting wheel as a micro-bevel (i.e., 2-5º greater than ⍺). That is shown on the top right drawing as the hazy area at the tip of the edge. (For more information on this, see the Pocket Knives page.)
