Abstract
Abstract A hair comb sized similar to a credit card and structured to meet the flexure requirements of being housed in a wallet or credit card holder is disclosed. The comb is formed of a thin, relatively rigid, but slightly flexible, rectangular sheet of plastic having teeth located along one edge. The length of the teeth near the ends of the comb decreases, while the tips of the teeth are maintained in alignment. Changing the length of the end teeth in this manner, plus the inclusion of relatively wider teeth and fairing areas between the teeth to significantly increase the strength of the teeth, reduces the possibility of teeth breakage. The faces of the side of the hair comb, opposite to the side from which the teeth project, includes opposed tactilely textured depressions that assist a user in removing the comb from a wallet or credit card holder.
