Abstract: A straight razor has a handle portion and a disposable multi-blade assembly with at least two blades as the cutting edge on at least one of its sides. A molded guard portion at the bottom of the blade portion prevents the blades from cutting into the skin by keeping the cutting edge limited to the surface in common among the sharp edges of the blades and the bottom guard portion. The blade assembly may be connected to the handle by a pivotable blade holder attached to the handle. The blade holder is attachable to disposable blade assemblies at one end of the blade assemblies. A tube-shaped handle may be directly attached to the blade assembly that slides over the blade to form a handle on either ends of the blade. The handle and the blade holder portions may be made of disposable materials and the blade assembly is permanently attached to the blade holder so that the entire multi-blade straight razor is disposable.
