According to Tom:
"Scales are made from a product called Recon (reconstituted) Stone, The material is made by combining stone dust from quarrying and fabrication (previously a waste product) into a binder and casting it into bricks. We slice the bricks, then grind, cut, file, and polish into the finished piece. This particular pattern is called "Webbed Turquoise". Approximately 40 other patterns are being manufactured currently."
Fantastic work Tom! I'm sure this knife will go over well at the show!
