Abstract
A single hand-held scissors for cutting hair including a first and second member pivotally interconnected intermediate between their ends via a hinge joint. The end of both members having ring-like finger holds formed integrally with handles. The opposite end of the first member is formed as a first jaw containing an integral longitudinal recess for releasably securing a straight-edged razor blade therein. The second member has its opposite end formed into a second jaw containing a longitudinal recess in vertical alignment with the recess in the first jaw. The hinge joint includes cooperating face having laterally extending shoulders which engage to limit the opening and closing of the scissors. The shoulders for limiting the closing of the scissors prevent the razor blade edge from engaging the lower edges or bottom walls forming such recess in the second jaw when smoothly cleaving hair disposed between the jaws.
