Philishave was the brand name for the electric shavers manufactured by the Philips Domestic Appliances and Personal Care unit of Philips (in theU.S.A., the Norelco name is used instead). In recent years, Philips had extended the Philishave brand to include hair clippers, beard trimmers and beard shapers. Philips used the Philishave brand name for their shavers from 1939 to 2006.

The Philishave shaver was invented by Philips engineer Alexandre Horowitz, who used rotating cutters instead of the reciprocating cutters that had been used in previous electric shavers.
