Just a quick one this!
Over this last few months, I have noticed that my Gillette 7 O'clock blades seem to be lasting a lot longer than they did. I used to be lucky to get three shave per blade, but now seven or eight is not uncommon. The record being twelve shaves.
I suspect this is all down to my getting better at shaving over time?
Oops, just discovered an almost identical thread in the blades section, DUH! Sorry guys.
