Anyone use the Derby Professional blade? The ones I have are single edge in that it looks like a double edge split right down the middle. I use them as a double edge in my DE razors. I just drop one of these half blades on each side of the razor and when you tighten down the gates, the blades are locked in just as if it were a regular DE blade. Anyway, the saves are great and last me about five shaves. I bought them at Sallys for around $9.00 for a 100 pack, which used the way I use them, it equals out to 50 blades.
