ABSTRACT:
A folding blade knife constructed so that the knife blade can be opened or closed with one hand. The knife includes a handle composed of two side members that are assembled in a spaced relation to provide space for a blade. A blade is pivotally mounted in one end of the handle for movement to an open or closed position. The blade has an elongated slot cut therein and the slot is located in the end of the blade mounted in the handle. A locking lever is pivotally mounted in the elongated slot in the blade. The lever has a release button formed on one end and a locking button formed on the other end. A pair of locking recesses are formed in the interior surface of one of the handle sides members. These recesses are located adjacent to the end of the handle where the blade is mounted. The elongated slot in the blade, and thus the locking lever, are positioned so that the locking button of the locking lever will engage the locking recesses in the handle. The release button on the other end of the lever can be depressed manually to move the locking button out of the locking recesses. A portion of the elongated slot is a through slot that is enclosed in the handle and it receives the locking button portion of the locking lever. The remainder of the slot is a blind slot whose end is located outside the handle and it receives the release button of the locking lever. When the release button is pressed the lever is pivoted and the locking button is moved out of the locking recesses in the handle. A coil spring is positioned between the release button end of the lever and the bottom of the blind slot to bias the locking button of the lever into the locking recesses in the handle.
