Abstract
Abstract A purse theft protection device for causing a purse snatcher to release his grip on one of a pair of cylindrical ostensibly ornamental spacer elements connected in longitudinal spaced relathionship at their lower end to the upper frame of the purse and at their upper end to one end of the purse handle, leaving a sufficient distance between the upper purse frame and the ends of the purse handle to permit the purse to be firmly gripped by its handle for carrying the same in a conventional manner. Each said cylindrical ornamental spacer element incorporating a plurality of circumferentially spaced concealed radially disposed knife blades at the lower end portion thereof which become exposed and travel upwardly along slots provided in said cylindrical spacer element and cut the hand or fingers of a purse snatcher who may attempt to snatch the purse by manually gripping either of said ornamental cylindrical spacer elements and attempting to jerk the purse from the hand of a lady carrying said purse by its handle in a conventional manner.
