Abstract
A bladeset for a hair clipper includes blade teeth configured to guide hair strands toward a cutting zone and to retain hair strands in the cutting zone. By more effectively guiding and retaining the hair strands into the cutting zone, more complete hair cutting may be achieved. Another feature of the present self-cutting hair trimmer is a housing configured to provide a cutting line associated with a generally elongate handle, which in turn provides a bladeset angle of attack substantially perpendicular to hair to be cut on all parts of a self-user's head or a subject's head when the present trimmer is held by a user in either hand.
