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.

Abstract: This invention relates to a utility knife having a handle with two or more angular bends. The utility knife has replaceable blade, which may be retractable, clamped in the nose of the knife handle. The knife handle is hollow and separable to accommodate the storage of spare blades in the handle. Most utility knives either have handles which are substantially straight or which have a single angular bend. These knives are more limited in their application or produce difficulty in cutting materials in an obstructed area. A knife having a handle with two or more bends enables the user to cut materials in close quarters or in obstructed areas with greater ease. Different handles provide greater reach or leverage under different circumstances. An alternative knife includes a handle with two or more angular bends, one of which is adjustable. This allows the user to select a configuration that offers optimum reach and leverage.
