This is the original push-button knife, and it still uses the same innovative and patented design . To use, simply push the button at the rear of the knife, swing the knife open, change the blade (or blade edge) and squeeze the knife shut. When you hear the knife ‘click’, you know it is closed and locked. It won’t open unless you push the button. Slotted razor blades are not supplied.

Slim nose profile provides a good view of the cutting edge
Thumb stop provides for safety and permits increased cutting pressure and control
