I know what you mean about taking off too much wood C.S.Graves. I have made a lot of primitive bows, and I only have a few survivors. It is very easy to reduce a nice 45 pound bow to a 25 pounder with over-enthusiastic use of a big blade. Sometimes I've gotten away with using a hatchet (nowadays it might be a khukuri) for the whole job....but it is probably better to take off the last few hundreths of an inch with a scraper or something.
