Support BladeForums! Paid memberships don't see ads! Searched everywhere and can’t find a definite answer to this simple question. When using the Ken Onion Worksharp blade grinding attachment and setting an angle. Are the angles per side or made to be inclusive? I assume the setting of 17 degrees would be per side (34 inclusive) instead of (8.5 per side for 17 inclusive) but not 100%. Can anyone confirm which it is?
