[quote=Markus Nyman]Rounding the back of a paring chisel or slick ever so slightly would have the effect of making it a little less prone to dig in at the corners. In plane blades, which are mostly used bevel down, it is the bevel side which is cambered slightly.

Yes, a good point I believe I over looked. I do not sharpen my plane blades the same as my slick. I don't know what got into me!

When it comes to mortice and tenon work, I find the axe and slick do most of the work, other than crosscutting with the saw.

DL, any specific sharpen points to the Stichaxt? As it is used in reference to an axe, is it sharpened in a similar manor?
