I agree...the MK3 has a nicer blade profile AND it's bead-blasted or otherwise finished very nicely. I didn't know the original BM151 was hollow ground. I would say you couldn't go wrong with either steel because, in the end, if you don't test them extensively, side-by-side, you won;t notice a difference between the two (steels). At least, I wouldn;t notice and I have knives in both steels already.

I don;t know if you're like this or not RedFlare, but I am: the Ritter knife is special because of the way the blade is shaped, finished, and engraved as a Doug Ritter knife. It costs more than twice the BM fixed grip but with every knife, at least with me, there's something to say for aesthetics. I look at them alot and admire them and so, though I don;t own one yet (and might never) I'm one who is willing to spend a little extra money for "just a little extra" knife."

With steels as good as S30V, 154CM, M2, A2, D2, even the old carbon standard 1095, the steel takes a back seat to design & aesthetics.
