I shave every single day--including weekends. Today was shave 62. I think the key is good beard prep--shower/Proraso Pre, uberlather and good technique. I don't have a super tough beard and I usually do only one pass. The results I'm getting now are not BBS, but acceptable.
Derby (62)
One pass and accepting a shave that is not BBS differs from my shaving and might be a part of the high count. I have tried to do only one pass but I don't feel comfortable with that!
But still, 62 shaves with a Derby, that's definitely impressive .
Note to self: have to try out Derbys again instead of relying on old memories!
