Hello Ben,
Yes, I found CA to be a great binder for the turquoise grains.
A fellow Tradganger e-mailed me for more information, and here is a copy of my response:
You can get the "ground turquoise" by searching amazon.com. I purchased one of fine ground turquoise "powder", and another pack of turquoise "grains". It's up to each knife maker's choice, but I prefer to use this stuff on stabilized resin impregnated woods. First, I clean out the gaps to be filled,and then I coat the inside of the gap(s) with water thin cyanoacrylate adhesive. Next, mix small amount of turquoise (powder and grains) with extra thick gap filling cyanoacrylate to make about 1/4 teaspoon total of the paste (with consistency of strawberry jam) to apply into the wood gap, you must be ready to work fast, as the paste will start to harden in less than three to four minutes. If the gap is rather large, just mix another batch and keep filling. I then sand and plastic polish the handle like I would any other stabilized wood knife handle.
