Holes are drilled for the pins as well as some additional holes to reduce the handle weight.
For handle material I have chosen Acrylester Abalone, a synthetic product popular with pen turners. It should buff up and look like a polished stone.
Two pieces of black fibre spacer make for nice contrast in the handle. After drilling out the scales, I have pinned it here with wooden dowel.
Here's a shot from the light box with the sheath made.
