I heard about these a couple years back, but haven't really seen them around. I got a chance to pick some up, so I thought I would share some information and pictures. Most images link to a larger version if you are trying to read packaging or see details. They came out as dual blade cartridge razors were starting to pick up steam. This was a creative way for Schick to cash in on the "more blades is better" notion. Basically it is a regular DE blade, and a slightly smaller DE blade, with a thin spacer sandwiched in between them. I love the quote from the packaging: "New Schick II Double Edge twin blades for a better shave without changing razors." Schick advertised that they fit all double edge razors, but in reality, the head geometry could make a big difference in whether or not the second blade actually touches your face. Because there are two different size blades, there is a top side, and a bottom side, and it is important they are put in the razor properly. In the razor, as the head tightens down, and the blade flexes, the blades do space just a little bit, but there is no way for the soap/whiskers to flow through like they do on a cartridge razor, so regular rinsing is necessary. Sorry, it turned out to be very difficult to get good pictures of the edges. This morning I shaved with one of these, in the Schick Platinum razor in the picture above. I didn't have high expectations. Surprisingly, I got a great shave. I think it was more the fact that it is has a good sharp and smooth edge than the fact that there are two blades, but it was a very nice shave. I am looking forward to experimenting with these in some different razors to see what kind of a difference it makes. Too Long Didn't Read: more blades = better.
