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.

Generally, the present invention provides shavers that are particularly applicable to shaving a user's head, but that may be utilized for shaving any part of the body. More specifically, a shaver according to the present invention has one or more of the following elements: a mounting pivot with a rotating piece where the mounting pivot is on the bottom surface of the body and extends toward the front end of the body, and a wheel rotatingly attached to the bottom surface near the back end wherein an axis of rotation of the wheel is parallel to a cutting edge.

A top portion extends from an upper end of a handle. The top portion is curved from the front to the back. A clearance is located between the back side of the razor head and the front of the top portion of the holder. The clearance between the back side of the razor head and the front of the top portion is changed by means of a pivoting mechanism such that, when the razor head is at the neutral position, the clearance at a position separated from the cutting edge is greater than the clearance at a position in the vicinity of the cutting edge. When the razor head is moved from the neutral position to a specified movement position, the clearance at the position separated from the cutting edge is less than the clearance at a position in the vicinity of the cutting edge.

A two-sided back shaver handle has an elongated member. A blade attachment located on the inner side is at a blade end of the elongated member opposite a grip end. A sponge is wrapped around the elongated member on the outer side of the elongated member opposite a grip end. The sponge has a strap wrapped around the elongated member. An elongated sponge can be located in a direction along a length of the elongated member on an outer side, wherein the elongated sponge extends longer in a length between the grip and the blade end than a width between the left side and the right side. The elongated member can be s-shaped with a convex surface contour on the outer side between the grip and the blade end.

A safety razor shaves back hair of a user. An elongated back shaver handle has a grip and a blade end. A blade group has a sharp blade and a guard parallel thereto. A substrate structure is coupled to the blade end. The substrate structure is adapted to hold both the blade group and a support on a front surface with the blade group and the support spaced a distance. The blade group and the support each extend from the front surface of the substrate structure at a height sufficient to avoid loose skin of the user touching the front surface of the substrate structure. The support can be either a blunt protrusion or another blade group.

A safety razor for personal grooming having a handle, a cap, an attachment mechanism, a double sided base plate, and a double edged safety razor blade. The double sided base plate comprising a central aperture for enabling the engagement between the handle and the cap; a first side having a first angled blade-engaging surface opposite a second angled blade-engaging surface, the first and second blade engaging surfaces defining a respective first and second blade gap when the razor blade is secured between the cap and the first side of the double sided base plate; and a second side having a third angled blade-engaging surface opposite a fourth angled blade-engaging surface, the third and fourth blade engaging surfaces defining a respective third and fourth blade gap when the razor blade is secured between the cap and the second side of the double sided base plate.
