Two Leatherman Free Thumb Studs or Thumb Bars

You will receive two thumb studs of your choice, Straight Bar, Round Stud, or one of each as pictured. The Round Stud option is modeled after the thumb stud on the Garage 005 tool, which is a slightly larger diameter and in my opinion, more comfortable than the one on the ARC.

These thumb studs are designed to fit into the blade cutout and provide easy one handed opening of the knife blade.

The part is a press fit, and should stay put without any need for glues or adhesives. Since your blade may differ somewhat from mine, if it is a loose fit, or if you just want it to be extra secure, a tiny drop of super glue applied with a toothpick to the knife opening before inserting the thumb stud will secure it. The first time you insert it, the blade may shave the plastic. You can remove the thumb stud and clear the plastic shaving if you desire, then replace the part.

Edges are slightly beveled to eliminate sharp corners, but not enough to reduce the functionality.

These pieces are designed by myself, and 3D printed in matte black PLA on my FDM printer. The thumb stud option comes with T6 screws installed and the grooves are simply filled in with silver ink for visual contrast. Message me if you prefer them without the silver.
