I have a large sebenza 21 Carbon Fiber. My first CRK and was used. But it just came back from the CRK Spa and was in new condition. I was wondering if my action was normal as well. There is tension on the pivot but buttery smooth and hydraulic feeling. Really hurts my thumb to try and flick it open with no wrist. Once in a while i would get it but it hurt too much doing it enough times to work. With some wrist i can get it to flick out. But this doesn't bother me enough since it is very satisfying to open it manually with the stud. I like to move it very slowly into the lock up, it is very satisfying.
My opinion on the free action or one with more tension. In the past i've screwed up knives trying to adjust them. It didn't bother me so much since they were cheap knives. One was a Cryo II that i took the spring assist out and ended up bending the frame lock so now it barely locks the knife up. I won't even try to loosen a screw on this sebenza. Anything I want done will be sent to the factory for them to adjust and refinish/replace. I already see the blue thumb stub wearing off at the tip and turn silver. I'll send it in and let them do it and check the tension on the pivot. I see that they are so well crafted and made to be disassembled and put back together like it was new from the factory. They give you the hex driver in the box for that reason. But i just don't want to mess with it.
I heard some light sanding of the phosphur bronze washers on a fine sharpening stone, clean it all up and reapply the grease and you're good to go. Some put different grease that gives a more free pivot. Again i'm just afraid to touch it. And i also think that since CRK grinds the washers down until the pivot/lock up is perfect, i feel like you might remove enough metal to effect the pivot and create some play.
