Abstract

A set of hair cutting blades, for use with an electric buzzer, comprising at least one upper blade and at least one lower blade. The upper blade has a plurality of upper teeth, and has a short side and a long side. The upper teeth vary in length such that they gradually increase in length between the short side and the long side. The upper teeth also vary in height such that they gradually increase in height between the short side and the long side. The lower blade has lower teeth which are uniform in both length and height. The upper blade is mounted to the buzzer directly over the lower blade and the blades are reciprocated against each other to create a cutting action. By a preferred embodiment, left and right facing upper blades are provided which form a mirror image of each other such that among both of said blades the short side and long side are reversed.

Claims

1. A set of hair cutting blades, for use with an electric buzzer, comprising:

an upper blade having a plurality of upper teeth, a short side and a long side, the upper teeth vary in length whereas the teeth gradually increase in length between the short side and long side, the upper teeth vary in height whereas the teeth gradually increase in height between the short side and long side; and

a lower blade, the lower blade having a plurality of lower teeth which are uniform in length and in height, the upper blade and lower blade are attached onto the electric trimmer where the upper blade is located directly over the lower blade such that the upper blade and lower blade are reciprocated to rub against each other to provide a cutting action.

2. The set of hair cutting blades as recited in claim 1, wherein the upper blade further comprises a pair of upper blades consisting of a left upper blade and a left lower blade, among which the short side and long side are reversed.

3. The set of hair cutting blades as recited in claim 2, wherein the overall difference in length between the upper teeth at the short side and the upper teeth at the long side is substantially one quarter inch.

4. The set of hair cutting blades as recited in claim 3, wherein the overall difference in height between the upper teeth at the short side and the upper teeth at the long side is substantially one quarter inch.
