Abstract: A method for facilitated precision cutting of hair by one handed sectioning, combing and locking of hair into position for cutting and a device for effecting the method. The device comprises a combination of comb, sectioning and locking members arranged such that it provides for the rapid one handed sequential hairstyling functions of sectioning, combing and uniform locking of hair in position for cutting, clipping or trimming without the necessity of constant comb and finger manipulation and movement. A short comb, adapted to comb a straight portion of hair, is combined with a thin tapered elongated sectioning and locking bar. The comb and bar are hingedly connected and are movable relative to each other by use of a single hand and finger manipulation.
