Cutting assembly and trimmer comprising the same

Provided is a cutting assembly (100) for cutting hairs on skin. The cutting assembly comprises a guard plate (102) for contacting the skin. The guard plate has a first toothed edge (104A) which extends along an axis. The first toothed edge comprises guard teeth (106A). The cutting assembly further comprises a cutter plate (108) which is disposed on the guard plate. The cutter plate is slidable relative to the guard plate in directions parallel with the axis. The cutter plate comprises a second toothed edge (110A) extending parallel with the axis. The second toothed edge comprises cutting teeth (112A). The cutter plate and the guard plate are aligned such that the hairs are cut by the cutting teeth against the guard teeth when the cutter plate slides. The cutting teeth each include a cutting portion (114A) and a tip (116A). The tip is outwardly enlarged relative to the cutting portion in at least one direction parallel with the axis. The minimum space between adjacent tips is less than the minimum space between adjacent guard teeth. The tip thereby maintains overlap with at least one of the guard teeth during sliding of the cutter plate relative to the guard plate. Further provided is a trimmer including the cutting assembly.
