Quality Issue

I've had a handful of Sebenzas and all seem to come with slightly varying degrees of tension on the lockbar... Just like with anything else, I'm sure there is an accepted variance in tension set during manufacture. Some are more difficult than others to open.
 
Call Heather yesterday, ask her to add a double silver thumb stud, I think is better than 1 blue thumb stud from the factory..Hope I get it back next week.

Glad I read deeper into this thread. I just received my first CRK today - a Umnumzaan. What a gorgeous and solid knife. The action is quiet as a mouse and lockup real good at probably 65 percent. Yet no way can I open it one-handed and it is even difficult with two hands.




Update! - Problem no more a problem as after a bunch of opening and closing - works great one-handed')

Just get a call from Heather, My Seb is ready to ship, Hope will get here tomorrow or latest Monday, I will update with picture when I get it. :)
 
My Seb is here, took 2 week, the action is almost like butter now, and the double silver lug look much better than single blue lug plus they send me extra gift.

FYI, for those who love Sebenza, double lug is way to go.

Thanks..Heather

....I don't know why everybody here STILL keeps insisting that you take the knife apart and clean it, or polish the washers or whatever. That is *not* the problem....

This can be seen by fully disengaging the lock bar on an opened Sebenza, with the edge facing down. Typically the blade will swing downward either (a) by itself from gravity alone or (b) with very little pressure.

This illustrates most of the friction during opening/closing is from the lock bar ball bearing against the blade tang, *not* from the washers or pivot. You can polish washers until mirror smooth, and it shouldn't make any difference.

If it seems to make a difference, it's probably *not* from polishing the washers but some minute change in assembly tolerance or lubrication during the disassembly/reassembly.

Also the previously-posted video about how to open a Sebenza is wrong. It advocates putting the right edge of your thumb on the stud and sliding upward from the rear of the knife. Chris Reeve himself posted "When opening a Sebenza or Mnandi, use a sideways, sweeping motion with the side of your thumb against the lug": http://www.bladeforums.com/forums/showthread.php?t=730951

By contrast the video says *don't* do this. I figure the designer of the knife knows how best to open it.

don't do that. there's no need to sand paper the washers. you could potentially affect the tolerances that makes the knife great in the first place.

make sure your hand(usually ring and pinky fingers) isn't pushing down on the lockbar making it difficult to open or close. dont put your thumb on top of the thumbstud, put it beside and push up.

Most knives don't really care what lube you use, but CR knives seem to perform best with their own grease.

Plus one on that.
I have polished my washers before but it was lightly with flitz which shouldn't remove any metal.

technically, any sort of polish will remove the metal, but it's possible you removed less than the tolerance that CRK allows for. I would never polish or sand anything from CRK.
