Abstract: A multi-function razor cartridge that can be used for hair trimming and normal shaving has a housing including a retractable guard and at least one razor blade having a cutting edge. The razor cartridge also has a comb mounted to the housing that is movable by a user between a non-operable position and an operable position. When the comb is in the non-operable position the razor cartridge can be used for a normal shaving operation. As the comb is moved to the operable position for hair trimming, the guard is retracted so that it will not interfere with the passage of longer hairs between the teeth of the comb.

Abstract: A battery powered grooming tool is provided that includes a safety razor assembly adjoined to a hair trimmer assembly. Both assemblies include a housing. The housings may be separable or may be integrally formed. The trimmer assembly includes a motor operably connected to a moving toothed blade. The motor has a diameter less than 18 mm, a peak efficiency greater than 55% and an output torque greater than 0.8 mNm at peak efficiency. The grooming tool has a width less than 25 mm and a mass less than 80 g and the grooming tool is ergonomically familiar to a typical safety razor user.
