Abstract
In a shaving razor using a blade cartridge, the reusable assembly of the razor includes a guard element and the blade cartridge is designed with no parts located in front of the blade edge or edges, and when the blade cartridge is installed in the reusable assembly, the guard element of the reusable assembly becomes located in front of the blade edge or edges of the blade cartridge to cooperate with the blade edges in a customary way to stretch the skin and erect the beard hairs in advance of the cutting edge. The blade cartridge is also movable about two different pivot axes to improve the safety of the razor during use.
