    摘要： A blade cartridge including one or more blades fixed between a platform member and a cap member. The present invention provides a novel blade cartridge including one or more protruding members, or guard ribs, positioned proximate the skin engaging edges of the blades such that a portion of the blade adjacent the guard ribs has a negative exposure. The guard rib preferably has an arcuate contact surface and is narrow in thickness in a direction along the skin engaging edge. Preferably a plurality of guard ribs are evenly positioned along the blade cartridge. In addition to the guard ribs on the platform member, the present invention further includes protruding members, or guard ribs, on the cap member. The guard ribs on the platform member are preferably aligned with and substantially continuous with the guard ribs on the cap member. In a further embodiment, the blade cartridge includes a spacer separating the first blade and a second blade. In this embodiment the spacer has protruding members, or guard ribs, positioned proximate the skin engaging edges of the first and second blades.
