I'll have to give 'em a **** again after corking. Today I tried a Derby (corked) and it was the worst blade I've ever tried.
I finally decided that trying all these blades was rather pointless and ordered 100 RP's. I'm still planning to try Swedes and Wilkinson, but I figure life is too short to keep at bad blades. I've never gotten a bad shave with a RP (unless I used it too long) and 100 of them cost less than two packs of Merkur or Feather blades. What's not to love?
