Rink stippling on wood anatomical grips

Nifty detail on a recent Rink Formgriffe video at 1:25 minutes: https://youtu.be/ueQj3592CKM

I am a big fan of air chisel 1911 front strap stippling, but since I also have several Rink grips that I usually buy slightly large and have to fine tune I have a few tools and some Scherell oil to get the fit correct. Good to see how the factory does the details.

After I used the dreaded Dremmel with an engraving head, worked out well. I wish I had that cool tool they used.

It's just one of these and they ground points in the tip of the flat chisel blade.
Start with low air pressure and work your way up.
