vibrating function as discussed above reciprocating vibrating or oscillating motion razors referred to collectively herein as u201c vibrating razors u201d are described for example in u s pat nos 5 046 249 5 299 354 5 794 342 and 6 481 104 the vibrating mechanisms described in any of these patents may be used in the razor described herein if desired an example of a suitable vibrating mechanism is shown diagramatically in fig3 as indicated in fig3 the razor may include a rotary motor m powered by a battery b and an eccentric element e for imparting oscillating motion motor m e g an electric motor is housed within the handle and has an output shaft not shown on which is mounted the eccentric element e e g an eccentric weight energization of the motor results in high speed rotation of the eccentric weight and thereby vibration of the razor and the blade unit in particular the eccentric weight may be rotated at a speed of for example from about 5 000 rpm to about 10 000 rpm causing the cartridge body to vibrate with an amplitude of about 0 002 inches to about 0 01 inches the motor may be energized by a user by deflecting actuator 13 and thereby actuating a switch mechanism.
