Abstract
A bladeset is operationally connected to a hair clipper and includes a stationary blade and a moving blade configured for reciprocating laterally relative to the stationary blade. At least one of the stationary blade and the moving blade includes a base and a plurality of teeth extending from the base. The plurality of teeth includes a set of long teeth, each of the long teeth having a tip parallel to and spaced a first distance from the base defining a first cutting line; and a set of short teeth, each of the short teeth having a tip parallel to and spaced a second distance from the base defining a second cutting line spaced apart from the first cutting line. The first cutting line is farther from the base than the second cutting line.

A bladeset operationally connected to a hair clipper, the bladeset comprising:
- a stationary blade and a moving blade configured for reciprocating laterally relative to said stationary blade;
- at least one of said stationary blade and said moving blade including a base and a plurality of teeth extending from said base, said plurality of teeth comprising:
- a set of long teeth, each of said long teeth having a tip parallel to and spaced a first distance from said base defining a first cutting line;
- a set of short teeth, each of said short teeth having a tip parallel to and spaced a second distance from said base defining a second cutting line spaced apart from said first cutting line, wherein said first cutting line is farther from said base than said second cutting line, and
- wherein:
- each of said long teeth includes first and second cutting faces with a first segment which extends transversely from said base, and wherein one of said first and second cutting faces of said long teeth includes a second segment with a first tapered edge having a first end at said tip of said long teeth and a second end at said first segment, and said first segment of the other of said first and second cutting faces extends along an entire length of said second cutting face, such that consecutive long teeth of said set of said long teeth alternate which of said first cutting face and said second cutting face of said long teeth include said first tapered edge, and each of said short teeth includes a first cutting face and a second cutting face, said first and second cutting faces of each of said short teeth being parallel to one another;
- or
- each of said short teeth includes first and second cutting faces with a first segment which extends transversely from said base, and wherein one of said first and second cutting faces of said short teeth includes a second segment with a second tapered edge having a first end at said tip of said short teeth and a second end at said first segment, and said first segment of the other of said first and second cutting faces extends along an entire length of said second cutting face, such that consecutive short teeth of said set of said short teeth alternate which of said first cutting face and said second cutting face of said short teeth include said first tapered edge, and each of said long teeth includes a first cutting face and a second cutting face, said first and second cutting faces of each of said long teeth being parallel to one another.
