You might be surprized on the longevity side, when I was testing them I cranked one out to 14 shaves & got bored, As a rule of thumb they get tossed after 10 now or showing dullness get tossed earlier.I tried one last night in my RR GC.84 SB, a great smooth shave, used a lot of care above my lip, no against the grain there. 3 pass everywhere else, BBS, this morning feels a little closer than a Feather or Nacent. If Kai's will last 3 or 4 shaves+ may purchase more, never see them on a sale, a little pricey.
