Regarding the harsh corners, yes, I know what you mean, but they’re easy enough to soften with a diamond file, and I suppose it’s one less manufacturing step.

I finally tried the RP rasp and I am extremely happy with it. I am making a couple of kayak paddles right now and it has the perfect radius for the concave side of the curved paddle blades. I was able to perfectly even out the surface very quickly of all the ridges left by the bandsaw. It was also very useful at blending in the shaft of the paddle where it meets the blade. The paddle blade is a lamination of soft and hard woods, and it works well on both but better on the hardwood (maple and mahogany). For the soft wood (western red cedar), I just have to reduce the pressure I apply on the rasp otherwise being such a soft wood it digs in too much. The handles feel comfortable and I like that the rasp is symmetric and that I can quickly change from a pushing stroke to a pulling stroke. I was also surprised at how nice and smooth of a finish it leaves on the wood.

The only negative thing I found, is that if my hand slipped down the handle closest to my body when I am pushing on the rasp, it would get poked by the very sharp edges of the rasp blade where the tang bends. I rounded over those four sharp corners with a file, and it fixed it. I would send you a picture, but I do not know how to do that in a blog? Perhaps Liogier could round over the sharp edges in the future?

Thank you for designing the tool! I will used it often I am sure.
