King wood is very dense and from what I've seen it's also quite brittle. That being said, my best guess is that it would be fine for a riser on a t.d. Since the riser doesn't bend, it ought to work just fine. It would also be fine for face lams on a glass laminated bow since the glass does all the work and protects the wood from breakage. I wouldn't try it for limbs on an all-wood (even laminated) bow, however. I wouldn't use it for a riser in a one piece glass laminated bow either if the fade outs bend at all. Just my opinion. I have only used it in turning, not bowmaking.
