ABSTRACT:
A clipper for cutting hair strands includes a blade set which has a stationary blade having a plurality of stationary blade teeth arranged a row so that hair strands enter between adjacent stationary teeth as the blade set moves through the hair strands. The stationary blade teeth have angled side cutting edges and tips, and the side cutting edges of adjacent teeth form roots where they intersect.
A moving blade has a plurality of moving blade teeth which are also arranged in a row. The moving blade teeth complement the stationary blade teeth and pass across the stationary blade teeth in use to cut some of the hair strands. The moving blade teeth are relatively short, and preferably have tips which are flat. The moving blade teeth are separated by blade-like edge surfaces which are oriented in the direction of movement of the moving blade and are capable of cutting some of the hair strands which enter between the stationary blade teeth. The knife-like blade edges form a first line which is between a second line formed by the stationary blade teeth roots and a third line formed by the stationary blade teeth tips.
