I just received a NIB BM 710BK from knifeworks.com and the blade is marked different than the last one I ordered. The blade is just marked D2 rather than the last one that has D2BK1 on it. Is this a old knife with the old BK finish on it or did Benchmade stop marking new BK1 finished knives with the logo on it? The box is also marked 710 BK I don't recall if the box on the other knife was marked 710 BK1. I would be bummed if it does not have the new BK1 finish because from what I have read it offers better protection and wear resistance. I noticed on my buddy's 710 with the old finish it is marked D2BK on the blade so what's the deal?
