I've tried many brands over the years such as, Astra, Feather, Wilkinson, Gillette, Shark and a few others I can't recall but always come back to Derby's. It's the only blade where I don't get nicked, even with a more aggressive razor. I currently use these in my Shave Craft 101 SS razor and the Edwin Jagger DE 89 Chrome razor and always achieve excellent results.
