I love natural handle/scale materials, though a few have recently been made unavailable as a consequence of global legislation. But fortunately, with only a few exceptions, such legal roadblocks haven't been as impactful on most of the woods. While I am a lover of stone of all kinds, you just cannot beat woods for the variety and beauty they offer.
Back in the 80's, I had a friend who helped begin the movement toward stabilized woods that had great figure. He was one of the first, if not the first, to convince Randall to utiiize custom, highly figured stabilized wood on his orders. His name was Vince Bianchi (may the great man rest in peace) and his "compatriot" was Jim Frey who put the wood company together, and whom I believe still operates under the tradename "Wildwoods" - and is married to Sandra Brady, the scrimshander.
