I have found that it's best for me to dry the blade, but even then I may get one extra shave out of it...so I don't consider it being worth the hassle, so I leave the blade in the razor. Some blades I get 2 shaves, some I get 3, only blade I ever gotten a good 4th shave out of are the Feather blades. I'm not sure if there are any new production carbon blades, but I just use a DE here and there when in a rush. You can't rush a straight razor, I found out years ago...
