  • Knife lock mechanism
    Patent number: 5093995
    Abstract: A folding knife having a blade that can be pivoted into or out of a hollow knife handle. A depressible lock pin extends parallel to the blade pivot axis to normally extend through a notch in an arcuate edge of the blade, thereby holding the blade in a designated position (open or closed). Depression of the lock pin enables a transverse slot in the pin to register with the blade, such that the blade can be swung to a desired position.
