G'day gents, I've started using a Feather AC SS lately after about 8 years using DE razors. I've always used feather blades in my DE. I wasn't getting many shaves out of the pro guard blades I got so I tried putting in half a DE Feather blade into the SS (it works).


I can normally get 10+ shaves using a Feather in a DE, but when I put the same blade into a straight I only get 1-2 smooth shave before it dulls.


I like shaving with a straight shavette style but not if it's going to use 5 times as many blades as my DE.


Why the reduced blade life?


Cheers,
Pete
