I just tried a Bluebird Hi-Stainless blade for the first time. It kind of ate me up. Couple nicks, rough, patchy shave. It felt pretty sharp, but more dangerous-sharp than effective-sharp. The reviews are all pretty positive, so I think my skills just aren't ready for such a blade yet (numerous members pegged the Bluebirds as a step down from Feathers, which I haven't summoned the balls to try yet). One reviewer said the first shave is rougher than the rest, so I'll try another shave or two before I chicken out.
