Reviews: Fiskars 7861 Axe and Knife Sharpener
I have one axe which is fairly new, and hasn't felt the bite of a grindstone. That edge was sharpened to a beautiful point. I have an axe and a hatchet, decades old, which have been struck into the dirt many times and which have spent many minutes on a grinding wheel. This sharpener didn't even touch the point, and only demonstrated how poor an edge I ground out. So, worked beautifully for my Gerber and Fiskers axes.
The grinding wheel inside is just a stone cylinder with a V groove in it, held at an angle to the edge. Run the edge lightly back and forth through the V slot, and it's the rotation of the stone that sharpens little arcs into the edge. This doesn't need any down force. You can distinctly feel the drag when the edge has the same profile as the stone and it's time to stop.
