1. A razor assembly, comprising:
a razor cartridge including at least one shaving blade having a cutting edge and a blade housing configured to house the at least one shaving blade, wherein the razor cartridge is elongated along a longitudinal axis of the razor cartridge;
a connecting head comprising a first side movably coupled to the razor cartridge such that the razor cartridge is rotatable with respect to the connecting head about a first rotational axis parallel to the longitudinal axis of the razor cartridge;
a razor handle elongated along a longitudinal axis of the razor handle and configured to be coupled to the connecting head such that the connecting head is rotatable with respect to the razor handle about a second rotational axis perpendicular to both the longitudinal axis of the razor cartridge and the longitudinal axis of the razor handle, the razor handle further including a grip;
at least one first magnet or magnetic material coupled to a second side of the connecting head and configured to co-rotate with the connecting head about the second rotational axis; and
at least one second magnet or magnetic material coupled in a housing space of the razor handle and placed opposite to the at least one first magnet or magnetic material at a neutral position in which the at least one first magnet or magnetic material, the at least one second magnet or magnetic material, and razor handle are aligned with the longitudinal axis of the razor handle,
wherein the at least one first magnet or magnetic material located in the housing space of the razor handle is configured to move in a clockwise or counterclockwise direction away from the at least one second magnet or magnetic material according to a direction of the rotation of the connecting head moving away from the neutral position, and
wherein a magnetic force between the at least one first magnet and the at least one second magnet or magnetic material or between the at least one second magnet and the at least one first magnet or magnetic material biases the rotated connecting head toward the neutral position.
