I received a Gibbs Plus/Minus razor from one of my customers last week and thought it may be of some interest on the forum. It is a fixed head razor but has two different blade exposures. The Plus side is a bit more aggressive and the Minus side a little more tame. This particular model of Gibbs razor takes a proprietary blade while my Gibbs Click Pen razor takes standard DE blades. Leave it to the French. Fortunately, Harvey included about 100 of the Proprietary blades so I should be able to use this razor for "mourning" shaves for a long time to come.
