A replaceable blade unit for use in a shaving system includes an elongated body structure having a transversely extending guard surface on its forward edge for contact with the skin, a thin, elongated cutting member permanently fixed to the body structure with its cutting edge disposed parallel to and spaced from the guard surface in shaving relation to the latter, and coupling structure formed in the base of the body structure. The coupling structure defines two recesses that are disposed parallel to the guard surface and extend along the length of the body structure.
