Since returning to DE shave a couple months ago, I've been working my way through different samples. I'm very happy I upgraded to the Parker Variant. This morning I used a Perma-Sharp blade for the first time. Wow! I have to say that this was my best shave so far. I used a Kai blade for the last few days and that was also very good, but the Perma-Sharp was very smooth and sharp. I have a very coarse beard. I have some spots on my neck that are next to impossible to get smooth. Perma-Sharp did a really good job getting at those spots. It was as close to BBS as I've gotten so far. Definitely BBS on most spots. I still need to try Personna Red and some of the Rapira blades in the pack. But I would definitely say that Perma Sharp has been the best that I've tried for my beard so far.
