ABSTRACT:
A blade is provided for use in a hair clipper having a bladeset including a moving blade and a stationary blade, the bladeset being constructed and arranged so that the moving blade is pressed against the stationary blade for allowing the moving blade to reciprocate relative to the stationary blade in a transverse direction to a longitudinal axis of the clipper. The blade includes a base portion having a tooth end, and a mounting end opposite the tooth end, a plurality of teeth arranged in spaced, parallel relationship to each other and projecting from the tooth end, each tooth having a tip and a root opposite the tip and being joined to the tooth end. The roots are joined to the tooth end in spaced relationship to each other to define generally planar-floored channels between the roots for facilitating the evacuation of hair and/or hair clippings from a cutting area of the bladeset. Also, the teeth have a constant rake angle at least from the tip to the root, and the base portion defines a transverse hump area of constant radius designed for further facilitating the evacuation of hair and/or hair clippings from the cutting area.
