well, last week I used my silver flair tipped SS C4. This week is my 48-48 SS as I wanted to contrast the two. I'm using a Gillette silver blue again. Can it be that they feel like totally different razors? They do to me. I'm not sure if it's the weight or the handle or blade gap. Not better or worse, just different. Anyway, it was a great shave and I'm looking forward to the next 6.
