Abstract
A knife which has generally a blade and a handle wherein the blade folds into the handle; and wherein the handle has a first parallel plate and a second parallel plate which are secured to each other and spaced from each other by a spacer bushing and a fixed bushing to form therein a pocket into which the blade folds as it rotates around the fixed bushing. The fixed bushing has therein a slide hole into which the stem of a lock inserts. A biasing spring is installed in a bore in the stem and bears against a shoulder inside the stem and against a spring plate affixed to the outside of the first parallel plate, thereby biasing the stem and the lock through the second parallel plate. A button on the outside of the second parallel plate passes through a button hole therein, and the button is affixed to the end of the stem. The lock has a lock pin which protrudes through the first parallel plate and engages one of a plurality of lock pin holes in the blade securing the blade in the desired position. To release the blade, the button is pressed, thereby disengaging the lock pin from the lock pinhole and allowing the blade to be repositioned and again locked in the new desired position.
