I think CRK has been moving toward cutting cost and labor in the switch to the 25 Sebenza so it would appear in the Umnumzaan that he'd follow suit. It's good business and if the knife stays up to par in quality (unknown) then well done IMO.
So with all of this supposed cost cutting, making every sebenza 25(and umnumzaan) pivot like every other knife out there, we can expect a little break on the price?
Seriously though, I thought the pivot bushing system was one of the things that make CRK knives WORTH the premium.
