16 Claims

1. A safety razor comprising a handle and a blade unit with a guard, a cap and at least one blade, the blade unit being mounted to the handle for movement relative thereto about a pivot axis for following skin contours during shaving, the blade unit having a normal rest position towards which the blade unit is biased by a return force when pivoted away from the rest position, wherein the return force comprises a magnetic force generated by first and second magnets that are moved relative to each other in response to pivotal movement of the blade unit relative to the handle, and the return force increases in magnitude as the blade unit pivots away from the rest position, and wherein the blade unit is pivotally carried by a pair of opposed arms extending from a hub, and the second magnet is positioned at the hub.
