Abstract
An attachment comb for use with a hair clipper that includes a series of teeth with lower peripheral surfaces of a particular curve that are configured for comfortable movement along the surface of a subject's head, and where the teeth are also preferably proportioned in such a manner as to permit the hair to be uniformly trimmed to relatively long lengths of an inch or greater. Specifically, in the present attachment comb, at least one of the teeth preferably includes a widened rib portion that extends along at least a portion of the length of the lower peripheral edge of that tooth. In addition, the lower peripheral surfaces of the teeth are preferably curved into a half-teardrop shape that includes both a concave curved surface and a convex curved surface. Finally, the teeth may be flared outwardly as they extend away from the base portion so that the hair being cut can be directed toward the cutting blades on the hair clipper.
