I've got my great granddad's old lipped adze, and it's in pretty good shape, and I want to use it and become proficient with it. I'm having some trouble sharpening it. I'm good at sharpening chisels and plane irons, and passable with gouges, but I'm not really sure what to do with this. The way that it is currently ground, the "lips" are trailing the center span of the blade. In other words, they make their cut after the body of the blade has made its cut. Is this right? Or should it all make contact at the same time? Any tips on sharpening and use would be greatly appeciated. As it is, I use a power plane for dubbing, but there are times that I'm confident that my great granddad with his adze could have gotten the job done alot more quickly. What kind of self-respecting boatbuilder isn't skilled with an adze?
