A safety razor comprising a handle and a blade unit, said blade unit comprising 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 the 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 magnetic elements 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.
