So, I just tried Perma-Sharp for the first time. Used Parker Variant OC set to 2, which is the lower of the settings I use with Astra SP (2-2.5), and gives me a proven benchmark performance to check against.
At the first shave, Perma-Sharp was excellent - sharp and smooth. I’d say it indeed falls in between Feather and Astra. That said, I wouldn’t pay twice for it over the already great (for me) Astra, as it doesn’t provide a night and day difference. Now, let’s see how it performs in other razors and how long it lasts. I typically bin Astras after 5th shave, and I could probably squeeze a couple more before it starts to deteriorate.
