Stabilized and textured leather handle scales

[bunghole]

Any idea of how they do this? I've thought this might be a cool scale material, but never really had a good idea on how to make it work...

I'm not sure if this is how they do it but with stones they sometimes stabilize them with a "plastic" in gas or vapor form under a vaccuum.

Maybe they are done that way? Just a guess.

It seems like a nice material for a handle.
