Ya I'll have to take pictures the have a decent shank that has a plastic color coded ring around them they could be out into a Dremel or maybe a larger pin vise but they are built in a way were they could easily be hand turned and drill fine, they are how ever very fragile and don't take side loading well at all case in point my hand.

I have some where if I can find it a piece of shrapnel from a grenade that clipped me right above the ear. The shrapnel came from a US grenade so no purple heart a few inches probably woulda made a significant difference in my presence today but shit happens in the sand box I still got my 90% precent from the VA in the end.

It would be hard to model with a stump
