Thanks Jeff, can you describe the action you use when grinding a convex-edged axe - do you move the tool parallel to the edge, or perpendicular with some sort of rocking motion?
Okay, that was a little flip. But, in fact, it's about what I do. I work across the stone, parallel with the edge, three or four passes, with the edge off the stone, in effect working the back of the bevel. Then I raise the angle slightly and repeat. I keep doing this until I am up at an angle where the edge is being ground, then I work back down to the back of the bevel. Turn the head over and do the same on the other side. On a typical axe head, I probably work 4 "sections", but don't work at keeping them distinct...in fact you want to make sure you don't work at exactly the same point too often, with the exception of the work right at the cutting edge and (less critical) at the back of the bevel.
