About this print
A 3D printed pocket knife featuring a liner lock mechanism, a drop point blade and a thumb stud for one-handed opening. The liner lock functions in the same way as a conventional folding knife, releasing by pressing the liner sideways with the thumb. It serves as a functional proof of concept for printing working mechanical assemblies. PLA is suitable for a prototype print, though PETG offers greater flexibility and durability for a part that must flex under repeated use.

Intro
-----
The goal of this project was to create a pocket knife that was able to be 3d printed that utilized a liner lock. Neat proof of concept, no?
Knife blade is a drop point. Thumb stud is included on the blade. Cutting surface is roughly 2.7" long. The knfie can easily be opened with one hand and close with one as well. To unlock liner lock, simply push to the side with thumb, just like on a real knife with a liner lock!

I have printed this and it works fine. Lockup is solid. Changes in future versions include a lanyard clip as well as different blade profiles (tanto, clip point, straight back).
Knife pictured is a version before this release and lacks an extra washer, and some refinement. Regardless, your knife should print fine.
