ABSTRACT:
A self-defense knife has a handle and a blade. A user of the knife preferably holds it by the handle such that the blade extends toward the elbow of the user. The blade has a blunt edge and an opposite sharp edge. The knife is preferably held, more particularly, such that the blunt edge rests against the soft underbelly of the user's forearm. By holding the knife that way, the user is less likely to harm him or herself during use, and is also more likely to maintain the sharp or cutting edge in proper position for fending off an aggressor. The blunt edge is given a shape and arrangement that generally defines a reverse curve of the curve defined by the user's partly flexed wrist and forearm. The curve of the blunt edge thereby closes up a possible gap that could exist between the blunt edge and forearm. That way, an aggressor cannot grab the wrist of the user without also grabbing the sharp edge. Also, when the user raises his or her forearm to ward off a punch or the like from the aggressor--which presumptively is a normal reaction for most people--the cutting edge is positioned to catch the punch. The aggressor would thereby be cut and disabled, or at least be deterred from continuing his or her assault on the user. The contact between the blunt edge and forearm also effectively forms a unified mass which acts as a shield for the user from lunges from the aggressor, except that this kind of shield includes an exposed knife edge, the contact between the forearm and blunt edge also thereby giving support to the blade to buck or oppose the momentum of the aggressor's punch, kick or lunge and the like.
