If there is one thing we agree on, its that Gillette's undated Superspeeds from the late 40's are some of the most wonderful razors in the constellation. The un-notched is a bit more difficult to come by and this summer I was lucky enough to find one in a lovely little antique shop in the Berkshires. But which one shaves better? Surely the differences will be subtle. I'm anxious to find out. So beginning tomorrow, the "face off" begins. Blade of choice: Shark Super Stainless. I will keep you posted.
