Support BladeForums! Paid memberships don't see ads! Ha, i was wondering if anyone would notice, good eye. That is a rare bird indeed. It left the factory like that. Purchased new from dealer, i am second owner but it has box and birthcard from 2nd quarter 08 which is in the transition from regular blades to the 21, so best guess is it got mixed up in the assembly batch. Its actually one of the smoothest Sebenzas ive got with perfect lockup, i rarely carry it since im sure there isnt another one out there like it that ive seen, but recently i figured what fun is it doing me in a safe so ive been sheath carrying it for a few weeks.
