A razor includes one or more blades that are directly or indirectly heated by RF energy. A control circuit is connected to and operates a high frequency (HF) generator and a HF power amplifier (HFPA) for generating radio frequency (RF) energy throughout a range of controllable power levels. The generated RF energy is guided by a wave guide from the HFPA to a resonance chamber (i.e., band pass filter cavity). The RF energy is radiated from the resonance chamber towards the one or more blades which absorb the RF energy, thereby causing the temperature of the blades to increase. An energy source provides the electric current required for operating the control circuit, the HF generator and the HFPA. In another embodiment, the RF energy is radiated from the resonance chamber towards a heating element that increases in temperature and heats the blades by thermal conduction.
