An oscillating blade razor for removing hair projecting from skin is described. At least one cutting blade is mounted to a shuttle which is nested within a cartridge such that the shuttle is free to move in a longitudinal oscillating motion relative to the cartridge. The cartridge is removably affixed to the head of the razor in which is disposed a cantilever type bimorph piezoelectric motor, the proximal end of which is fixedly mounted in the head such that the distal end engages the shuttle and drives it in a reciprocating, oscillatory motion when the cartridge is engaged with the head and power applied. The head further incorporates the mechanism for engaging the cartridge. In one preferred embodiment, the cartridge incorporates electrical contact means for sensing the end travel of the oscillating shuttle. The head is disposed on the distal end of a handle which contains a battery, an on/off switch, and the electronic means for driving the distal end of the piezoelectric motor in an oscillatory motion. The proximal end of the handle provides a means for replacing the battery.
