Every time I read that some are getting 20 or more shaves with the same blade, I'd like to also know how coarse and thick their beards are,
whether all shaves are 3 passes and if they're all BBS. I'm going to see how many smooth shaves I get with this blade and follow up here.
Completely legitimate question. But there are a few shavers who get BBS shaves with exceptional longevity:

The main factors seem to be (1) exceptional prep and hydration, (2) low pressure shaving, (3) great technique. With concentration, a "two-shaves-a-blade" shaver can evolve into a "seven-shaves-a-blade" shaver pretty rapidly. The Excalibur Club is a great place to begin your exploration.
