Plans - Button Lock mechanical plans/drawings 6 pages by Don Robinson
Don Robinson is a heavily experienced Knifemaker, Tool & Die Maker, Tool Designer, and Manufacturing Engineer.
This one is my own unique design for a button lock folder. It has a titanium leaf spring that opens the blade about 90 degrees when the button is pushed. If the knife is held down for gravity assist, it will open all the way with a small wrist snap.
