I have just received a lot of 3 razors from ebay, one Max Dorner, one M. Jung and one Griffon XX 60 that says Carbo Magnetic on the blade. The griffon seems to have a magnetic charge. Is that the case with all carbo magnetic blades? whats a carbo magnetic blade in the first place? Anybody ever heard or seen this before ? ALso any added benefits of this magnetic charge?
