Chisels and slicks to 3"
plane blades straight
plane blades cambered to any radius, even just the corners
Lathe parting tools
Lathe skews, straight and curved
any double bevel tool
This is all "theory" at this point. I want to manufacture at least one prototype to verify that it works and to identify any tweaks that may be needed. Even a scale drawing does not assure tweak free reality. Note that the blade can be held off center of the pivot by simply tightening one side more than the other. The frame can be flipped over and put back on the pivot post (not shown) for symmetric sharpening a double bevel on straight, skew, or curved edges. The pivoting is limited or eliminated by the little thumb screws. There is a tick on the heads to allow equal or asymmetric pivoting.
