ABSTRACT:
A pair of hair trimming shears has two pivotally connected blades with integral handles. Each blade carries a plurality of teeth which project upwardly from the surface of the blade; when the blades are closed upon one another, the tooth peaks on one blade engage the roots of the teeth on the other blade in meshing engagement. The teeth are of irregular triangular cross-sectional configuration, which produces a non-uniform, zig-zag cut line that disappears when combed. Thus, the shears permit shortening of hair length without creating undesirably defined cut lines.
