I had not heard of this before. A two blade cart by Gillette called the SkinGuard. But seeing this has me wondering how a head to head with this razor and Gillette's single blade cart offering, ironically named the Guard, would turn out. I'm not a cart guy but there are the rare times when a cart is the only thing I have time for. I've used the Guard and while I would never say I love it, or even like it, I found it's shave to be acceptable in a pinch. I'm just intrigued by Gillette's offerings. The Guard, with one blade. The SkinGuard, with two blades. The Mach 3, with three blades. And then all of Gillette's five blade offerings. Clearly trying to cover all the bases. But none of them as well as a solid double edge. Anyone have experience with ALL of these?
