Abstract
Abstract A hand-held defense weapon provides a first and second pair of shafts which are connected together at a common pivot located at the central portion of each shaft. A pair of handles are respectively on one end of each shaft and a pair of blunt elements are mounted on the other end of each shaft opposite the handle. A third shaft is connected to the common pivot at one end of that shaft with the shaft carrying a blunt element at the other end. The three shafts are thus independently movable with respect to the pivot and with respect to each other so that the apparatus can be positioned between any selected fingers of a user's hands, the shafts collapsing with respect to each other for storage to a position where the shafts are generally aligned side by side. The blunt elements can be removable to expose tips which are "tooled" such as Phillips, or flat-head screwdrivers or the like. Preferably the blunt elements would be spherical members threadably attached to the ends of the shafts.
