I reprofiled a D2 Camillus CUDA EDC (from A.G. Russell, only source with D2 blade I believe) using sandpaper. It was actually pretty easy. Because the blade is recurved, I mounted strips of sandpaper on a 10-inch section of ¾-inch dowel, using Elmer's spray adhesive. I clamped the dowel in a bench vise and tilted it to 17° with a protractor. It would have been easy enough to make two of these dowel and sandpaper units, V-stick style, but I have a swivelling vise, so I just did one side of the blade until I had an even bevel then turned the vise around and did the other side. I think I used 110 grit, something like that. This system is incredibly versatile and effective. I'm not so hot at freehanding, but I can maintain a vertical pretty well. When you're reprofiling like this with a coarse grit sandpaper all you want to do is get the blade hogged down anyway, then run your usual sharpening technology. Actually the sandpaper on dowel method can take you through to the finished edge if you want, it's just a little tedious cutting strips from finer and finer grits and mounting them on the dowel.
