Foil  / Reciprocating : The  head contains linearly arranged  driven by a motor to move back and forth (reciprocate) at high speed. A thin, stationary foil with slots covers these . Hairs passing through the foil's slots are cut by the oscillating  beneath.

3. Main Types

Housing & Grip: Ergonomically designed for comfortable handling, often non-slip and easy to maneuver.

Power System:

Rechargeable: The mainstream type, uses built-in lithium-ion batteries, often supports quick charge (a few minutes charging provides one full shave) and  operation.
