I always used to keep track of the number of shaves per blade. I found that I would expect it to get dull by a certain time so I may have thrown them out early, or vice versa, using one too long expecting it to still be good. Nowadays I throw one in and pitch it when I don't get the expected results after my normal 2 pass face/3 pass neck with touchup. I'm pretty sure I usually get a week or so per blade but honestly couldn't tell you how many times I've used my current blade. I think this has been key to getting so many outstanding shaves in a row. Well, combined with the fact that I can now whip up a great lather with any soap/cream/brush I use. Each seems to be the best I've had. With no phony numbers to expect from a blade I find I'm actually paying more attention to the quality of the shave itself, which has been rewarding, rather than expecting 10 from a Polsilver or 5-6 from a Voskhod. The numbers don't mean a thing anymore. Thoughts?
