ABSTRACT:
A folding knife that is self opening when removed from a container such as a holster or pocket. The knife includes a handle and a knife blade with the blade hinged to the handle for folding from an extended, use, position to a stored position in a slot in the handle. A pin is formed on the knife blade adjacent to the hinged end, extending away from the blade when the blade is folded. When the knife is pulled from a container, the pin will snag the container just before the knife is fully removed, causing the blade to unfold to the use position. Preferably, the pin is hook-shaped with an end extending along the blade towards the blade tip. A releasable locking arrangement to lock the blade against folding while in use and for releasing the blade when desired for folding is preferably included.
