Abstract:

A one handed knife including a handle having upper and lower handle portions, the upper handle portion including an arcuate recess extending therethrough and the lower handle portion including a blade lock release extending therefrom. A blade is pivotally connected between the upper and lower handle portions and includes a thumb pin extending therefrom. A tension bar having a first and second ends is slideably connected at its first end to the upper handle portion and its second end extends through the arcuate recess and is connected to the blade. The one handed knife is movable between a first closed position in which the blade is partially positioned between the upper and lower handle portions, the thumb pin is positoned on a portion of the blade extending from between the upper and lower handle portions and the tension bar is in a first tensioned position at a first end of the arcuate recess and a second open position in which the blade extends from the handle, said tension bar is in a second untensioned position at a second end of the arcuate recess and the blade lock release is positioned to prevent the blade from pivoting towards the handle. The blade is caused to pivot from the first closed position into the second open position by application of a force on the thumb pin and away from the handle, the force being of a magnitude able to overcome the tension of the tension bar.
