My normal shave consists of 3 passes, WTG,XTG,and ATG, followed by a bit of blade buffing for a couple of rough spots. Results are a great BBS shave that feels fantastic. I average 4 shaves no matter what blade I use. I was just wondering if one would count each pass as one shave with the blade being used, or if the 3 passes and the blade buffing all count as one shave? I've not seen this question answered in the 4+ months that I've been a member. Is there a set rule on this having to do with blade life? Or does it just vary from shaver to shaver?
