A two way razor is disclosed having a handle, a bracket, and a shaving head mounting dual opposing shaving cartridges each comprising a plurality of razor blades, and a swivel mechanism disposed between the handle and the bracket for exchanging the positions of the first and second cartridges' positions, the swivel mechanism comprising first and second disks where a first disk has two projections at opposite ends and a second disk has two recesses at opposite ends, such that the projections and recesses engage to lock the bracket in first and second orientations with respect to the handle.

A razor treatment system includes a razor having a head, and a razor treatment device including a drum rotationally supported within the razor treatment device, at least two cam members supported within the razor treatment device, at least two guide members configured to cooperate with the cam members to expose the blade, and a first actuating member configured to effect rotation of the drum. The head includes a cover for housing a blade. The cover is configured to expose the blade. The razor interfaces with the razor treatment device to move the cover of the razor to expose the blade. Each cam member may define a cam track that guides linear retraction of the blade, rotational movement of the blade and cover, and linear extension of the blade into a position between the drums.
