Shaving systems are disclosed that include a replaceable shaving assembly and a cartridge connecting structure for connecting the shaving assembly to a handle. In preferred implementations, the cartridge connecting structure has a magnetic portion configured to help draw the cartridge onto the handle and retain the cartridge in place when the razor is not in contact with the skin, and a mechanical engagement that provides the necessary retention forces required to keep the system intact during shaving.

A shaving device comprising a handle, a support member, a blade cartridge retention frame, and a replaceable blade assembly. The support member is disposed about a first end of the handle and includes at least one arm extending outward from a yoke. The blade cartridge retention frame includes a blade cartridge retention frame magnet and is coupled to the at least one arm and configured to pivot about a pivot axis. The replaceable blade assembly includes a blade assembly magnet and a blade assembly body having a face with a razor blade. The blade assembly magnet and the blade cartridge retention frame magnet are configured to create a repulsive magnetic force therebetween to releasably couple the replaceable blade assembly to the blade cartridge retention frame.
