The 511 is listed as a 5.5" and the B6 as a 6.5", but they look very close to the same length. Just an observation, I'll be ordering both.
Yep me too, both Busse boys done good! However with Dan I can afford to buy two!! My one regret with the S6- was only buying one!
Anyway, the 511 strikes me as a great design for a small field/bushcraft/survival/utility knife. I'm looking forward to beating one up!
