Shaving assemblies are disclosed that include a blade unit, an interface element configured to connect the blade unit to a handle, on which the blade unit is pivotably mounted, and a return element disposed between the blade unit and interface element. The return element serves as interface piece, connector and pivot all in one. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems.

A razor handle assembly includes a gripping part gripped by a user, and a connecting part provided at one end of the gripping part to fix the cartridge. The connecting part includes a cartridge holder to which the cartridge is detachably coupled, and a holder clip which supports the cartridge holder. The cartridge holder is coupled to surround the outer side of an end portion of the holder clip.

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.
