    Scale Materials

    Question re: rubber-insert scales for the choppers produced the following quote from Nathan the Machinist:
    First I had to gain about 20 pounds because my old normal ass was too small for the amount of pain-in-the-ass. A full thickness sheet of micarta is skeletonized into a liner with bosses for the fasteners (can't clamp across rubber) and also solid at the front (can't kydex sheath rubber). This is run with the mounting holes complete. A rubber sheet is bonded to a standard liner to make it machinable. This is a sacrificial liner that gets cut away later. It's held down on a vacuum fixture and decked to get down to a clean bondable rubber surface and then machined to fit the skeletonized liner shape. There are hard earned tricks to machining rubber that I'm not going to share on the internet. This machined rubber is bonded to the micarta using an adhesive that ages well, will bond this kind of rubber, and doesn't loose strength with exposure to hand oils and sweat. It goes back onto the fist vacuum fixture (registered with pins) to have the mounting holes reestablished and re-machined. It then goes on to the final machining sculpting steps to be shaped into a handle, done in part with unicorn tears. Then I abuse alcohol and swear never again.

    Screws

    As of February 2021:
    Most knives are made with black oxide treated stainless steel fasteners, but titanium fasteners have been used.
