I just had my first shave with a Gillette 7 O'Clock Yellow. I typically use Derby's or Red Pack Personna's. This was my first foray into the 'sharper' blades. I typically use a Merkur 34C, but decided to try this blade in a more mild razor, a Gillette SS.
Although the Gillette was noticeably sharper than the Derby / RIP, it was a much 'rougher' shave. Despite the comfort (or lack) of the shave, the results were surprisingly very good. I was able to get great results with a 2-pass + touch-up shave versus my normal 3-pass + touch-up shave. But darn, it was a 'rough' feeling shave. I did get some minor razor burn, but I attribute that to my first shave with the sharper blade.
What has been your experience with this blade? Is my experience typical? I plan to try the Yellow in a couple of other razors before I pass final judgement. I also have a pack of Astra's waiting in the wing for a try-out.
