ABSTRACT:
For use with a hair trimmer of known design having coacting relatively oscillatable shear plates each provided with a series of generally V-shape cutting teeth and wherein a fixed shear plate is in position to engage the head of the party whose hair is being trimmed and an oscillatable shear plate is in contact therewith, a combination is provided of a removable comb plate clipped onto the bottom of the stationary shear plate and having a series of parallel comb teeth extending forwardly of the cutting teeth and spaced a predetermined distance from the shearing level whereby a person may cut his own hair using the trimmer with the comb attachment so as to cut the individual hairs at at uniform length. The invention includes a plurality of such detachable comb plates so that one might trim his hair say one-quarter of an inch long at a certain distance above his neckline, and then change to another comb plate attachment which would permit him to cut the hair for one-eighth of an inch length extending downwardly from the first cut and so on, to the neckline or other stopping point. A comb plate might be provided to cut to a length of 1/16th or 1/32nd of an inch.
