A metal-toothed comb is provided having elongated identical teeth each with a square cross-section along substantially the entire length, elongated edges of each tooth being slightly rounded, free ends of each of the teeth being slightly rounded, whereby the teeth are successively positioned juxtaposed in a common plane, with elongated edges of each tooth opposing one another, and the distance between the teeth being a constant 0.004 inch along the entire length of the gap therebetween, except for a relatively small portion proximate the distal ends of each tooth, which are tapered down to a rounded tip.
