A hair clipper is a tool used to cut the hair. It is a specific device that is usually compared to a scissor and a razor. It is powered by an electric motor that enables the blades to swing or oscillate back and forth. The motor can be one of these three types – rotary, magnetic and pivot. The rotary style motors are driven by an electrical current, either alternating or direct, while the magnetic and pivot motors are driven by magnetic forces produced by the copper wires wrapped around a steel inside the motor.

Most blades are made of rust-resistant stainless steel. Ceramic cutters are available and have the advantages of not heating up. It is more resistant to wear and tear than steel blades. However, ceramic is brittle and breaks easily, and these blades are more expensive to replace than steel blades.
