Nuts:
I've used bone for years and lately made a nut out of the dog chew toy called nylabone because the 50s nuts were supposedly made out of nylon. RS Guitarworks has a limited supply of what appears to be the original nut material for sale and I bought two blanks. The second photo shows the color diff between nylabone and rs blanks pretty well. The nylabone is opaque, but the rs is moreso.
