  • Publication number: 20190152079
    Abstract: A razor assembly includes a razor cartridge, a connecting head, a razor handle and a restoring force provider. The razor cartridge includes a blade housing for housing shaving blades in a first direction. The connecting head has one side detachably coupled to the razor cartridge. The razor handle includes a head adapter coupled to the connecting head to be rotatable about a rotational axis perpendicular to the first direction, and a grip extending from head adapter. The restoring force provider includes a first magnet disposed on another side of the connecting head which co-rotates with the connecting head about the rotational axis, and a second magnet disposed at a fixed position on the razor handle such that a magnetic force between the one or more first magnets and the one or more second magnets biases the connecting head toward a neutral rotation position with respect to the razor handle.
