I was asked by @sanibel686 how do i inlay shields in my slip joints, so here goes.
The shield us cut out of 1mm Stainless sheet, i have a good number of designs, some from old knives, some i drew myself.
The scales are marked with a pencil where i want the shield placed and clamped under the template in the jig. The templates were made from O1 tool steel, hardened but not tempered! This allows the cutter to follow the shape without causing any wear to the template.
A small 1.2mm cutter is placed in the mill and brought down to the surface of the scale. Set the mill to zero and bring down the cutter 1/3 of a mil. Move the jig around following the shape repeat until a depth of 1mm is achieved. Work slowly or the cutter will break!!!
Try the shield in the cavity, hopefully it should fit, but sometimes a bit of filing around the edges is needed.
Drill 2 1mm holes in the shield, cut the pins to length, countersink the holes and gently rivet the pins in place. Piece of cake!
Hope this helps, any questions please ask.
