Abstract

Method and apparatus for cutting hair of a person with a toothed curve about nine inches long which becomes a template at fixed locations during hair cutting determining the length and shape of the cut and using an electric clipper to make all of the cuts using the curve back as a guide, the curve having a simple curvature arced relative to a centrally located axis parallel to and spaced from the axes of the teeth of the curve. Cutting on the concave or the convex face of the curve. Supplying a plurality of curves arced on different radiuses, the curves with lesser radiuses removing more weight of hair than curves with larger radiuses. Providing a variable speed control for the clipper and providing blades with more or less teeth per inch to provide in operations like feathering a blade with less teeth per inch driven at a lower speed. Adjacent tooth surfaces on the curve being roughened to grip hair. The backing portion of the curve having a first pair of guiding surfaces on opposite sides to space the clipper blade from the teeth and having a second pair of guiding surfaces perpendicular to the first surfaces, at the opposite side of the backing portion from the teeth, to guide the clipper blade from end to end of the curve. A handle for the curve on the opposite side of the backing portion from the teeth attachable at either end of the curve or in the middle.
