SOLD Chittam (aka American Smoke tree) produces what is widely regarded as the world's rarest burl. This set is cut from an Exhibition Grade block and showcases the extreme chatoyance for which this wood is highly prized. Beveled bottom with main spring housing pin cut-out. The burl is dense, and well suited to everyday carry and as well as being a mic drop (or jaw drop) moment at your next barbeque :)
