Knife & Gun or WSSI are two reputable companies. Recently, I have made a handle from acrylic stabilized wood from a third. The block was not thoroughly impregnated and the drilling it was a nightmare, as it was clogging up drill bit as fast as I could clean it. From that time, only K&G or WSSIWSSI is the industry leader. They do the best job out there. Some home meathods produce fair results, but seldom get the penetration. WSSI uses methylmethacrylate, essentially filling the wood down tothe cell level with lexan (plexiglass).
