I haven't made a lot of hawks, less than a dozen. What I've found is that while the curly maple is traditional and beutifull, it won't hold up to heavy use. I just about wont use it after burying the head in a block of wood and snapping the handles. From what I understand the majority of hawks came from england as forgings and the local gunmakers who were mainly using curly maple for stocks used the same material for the handles. Most of the hawks that were used out in the rough and tumble soon got hickory or ash handles. They'll hold up fairly well to light use, but for unbreakable, go with hickory. Ash should be nearly as tough as long as it's straight grained. I've got a supply of straight grained swamp hickory that I'm letting age just for hawk handles. I've heard of competion throwers carrying extra handles with them so when they break one they can just change it out, but if it's straight grained hickory I can't for the life of me figure out how there breaking them, running over it with a dozer maybe? Early American stain from minwax looks good on hickory also. Ash, hickory and curly maple are traditional, though I imagine that any and every thing was used at one point or the other.
