Kevin,
I have never seen a guide for other uses, only seen (and felt) the results from axe men who knew their stuff. I did lumbering in the Rockies and the old guys could show you a lot. Their work is similar to what I see from Gransfors. Maybe I should make one off my axe before I ever sharpen it.
Looks like you are doing a great job. What I would expect from your other work. Thanks for the pictures.
Respectfully,
Jerry
