Amazon has micarta scales, corby bolts, brass pins, mosaic pins, etc. I use LePage Professional Speed Set Epoxy.
Micarta is fairly expensive......but it is bullet/dishwasher proof.
I'm in Edmonton for a while and I haven't been to Lee Valley for a long time so I'm going to see what they have along the line of knife making supplies.
The tangs on these knives are covered with micarta scales purchased off amazon.ca ($20 for a pair of scales)
