Ouch! This was my first shave tonight with a Personna Red blade, and man do I ever have a nasty razor burn. No cuts or weepers, just pain. I don't think anything was different about my technique. I even had a two day growth of whiskers, which usually results in a reasonably comfortable shave for me.
Used my EJ DE89, T&H Ultimate Comfort cream, a T&H silvertip badger brush and Proraso pre-shave. Even took a long shower before shaving, so my whiskers should've been nicely conditioned and ready to go. I did not use any pressure and did the standard 3 pass shave. Really nothing different at all tonight, except the blade.
Guess this is yet another example of YMMV. I know other people here like Personna Red blades. This was only the third blade I've tested: Derby blades, which were never consistent for me, Astra SP blades, which are the best for me so far, and now the Personna Red blades. I'll try a second shave with this Personna Red after I give my face a day to heal. I definitely won't be shaving tomorrow.
Are Personna Red blades considered sharper than Astra SP blades? It didn't seem sharper to me, but I'm still a newbie and perhaps not the best at judging the differences between blades.
