This was the worst blade I have used so far. I have tried 3 blades in 5 different razors. (I read that they shave better after the first shave). I cannot get this blade to feel good no matter the pre-shave/soap combo. I caught a glimmer of hope with my pre-war ball end tech but its not enough to justify using this blade.
I chose this blade because I can get the Derby Extra's to shave well in a couple of razors. Not enough for me to buy 100 pack, but enough that I keep a few tucks on hand.
My expectation was that the Premium would build off of the Extra but I was wrong. It felt like I was shaving with a cheese grater and my face looked like it had been shaved with a cheese grater.
