Thanks for the info.

I understand the differences in angles (razor vs axe ...).
My questions are :
- how to have a constant angle, at each sharpening session, with a Lansky system, as the position of the clamp on the knife will vary, thus the angle too will vary.
- what is the angle used on Doug's knife, out of the box ?

I don't want to completly redefine a new different angle on the blade, at each sharpening session.....
