<p>A precision hair clipper for cutting the hair of a subject to a uniform length which comprises a housing (11) defining a flow chamber attachable to a vacuum hose. At the inlet (14) of the housing a pair of reciprocating blades (15, 16) are configured to maintain a constant and equal flow of air through the chamber. Each of the blades is symmetrical to the other and features a row of parallel, sharp-edged slots (20). The row of slots of each blade is slanted in opposite direction to the row of the other blade so that their lateral oscillation results in a plurality of criss-crossing shearing edge action. The blades are driven by a pair of oppositely phased eccentric cams (23, 24) engaging openings in the blades. Selectable spacing of the clipper in relation to the subject's scalp is provided by a series of snap-on adjustable spacers (36).</p> |
