Joe Szilaski is my hero, his knowledge comes from the old school, he received his masters rating, years before the abs existed, in Hungary, making knives for fun and lots of complex mechanial stuff. He forged a tomahawk from a rail road spike, punched the hole and there was not enough scale to cover your thumb nail. He made Damascus steel in the 50's and thought nothing of it.
There is a lot of tallent there, his engraving is as good as it gets. Not only than all you have to do is ask him and he will share as much as you can understand.
I had been working on a design problem, I showed it to Joe, it took him less than two minutes using an eraser and a pencil to show me how to make my idea work.
