Hello , y'all
Since I have nothing to compare it to . I have a question for y'all . When your Zaan is closed is there play in the blade ,Where you can move it side to side ? Mine had it when I got it . There is no play when the blade is open . I can't dial it out , or its to tight to open . I'm just wondering if this is normal . Also any tips on tuning the pivot would be appreciated. .. thanx y'all
 
I just traded my Zaan but I did not notice any blade play when it was closed. Yeah, like most all knives, you could push it over so it moved to the other side of center, but I never considered that play.

To set the pivot tension, I would watch the centering when tightening the pivot. As soon as it hit center, I would stop. Open it a couple of times to check smoothness and let it sit for a few hours to let the loctite properly cure.
 
I just checked mine, and there is a little bit of play closed. It looks like it is the detent ball/lock bar moving a tad.

There is a lot of good advice all over about tuning in the pivot. For mine I tighten until it centers and fine tune from there. Tiny tiny adjustments make a lot of difference to try increments of 1/16 of a turn or so until it feels right and then let the loctite dry as advised.
 
Yes this is normal. A sebenza however, may not have any movement due to the pivot bushing.
 
My Umnumzaan has no play at all, open or closed, and perfectly centered. Smooth as glass to open or close. :thumbup:

I don't think there is any difference at all between the Zaan/25/Inkosi/Ti Lock pivot and a bushing pivot in terms of sideways blade play. If anything, the bushing would introduce increased potential for some type of play as opposed to solid fasteners, all of which have the same diameter hole in the blade tang.
 
Thanx y'all
When I received it new , I noticed the play . Let me clarify, in the open position there is absolutely no play , it is rock solid . When I say play ,I don't mean it was rattling around in the closed position. Just that you could jiggle it to and fro. But I figured once I opened it up and cleaned and lubed it , that I could adjust that out . But I found that I couldn't , if I adjusted the play out , it was locked shut . It isn't really a big deal . I was just worried that something was out of wack. And it wasn't in spec . Having no other specimens to compare it to . I came here to ask other owners . Y'all seem to confirm that it's normal . Further evident, that it came from the factory that way . As far as my 21 , the is no play what so ever . My zero tolerance flippers have no play either .. my zt bearing flippers are tuned like my 21 . Just crank it down all the way and you're good . My spyderco paramilitary and military have a slight amount of play when closed . I guess they have a similar system as the Zaan. So all is well ... thanx again .

I beg to differ. If you have a 21, close it and try to wiggle the tip side to side, then do the same with a zaan. You will notice a difference.
 
My Umnumzaan has no play at all, open or closed, and perfectly centered. Smooth as glass to open or close. :thumbup:

I am with socom1970, mine is spot on. Still as from the factory though. I have yet to dismantle it and so far action is smooth with no wobble in either close or open.
 
my new pivot zaan is a tab bit off centre but no play. it i centre it its really stiff. so its off a tad. still not sure if i love the naan or not. if anybody wants a straight up trade for their 21 large message or email me.
 
I'm confused ... there is no way my zaan has no play and is smooth .. it had play closed from the factory .. centering is no problem, it centers even if the blade is wobbling ... so what's the deal , is it normal or not .. with mine there's is no way to completely dial out blade play and be able to open the knife ... which kinda bothers me because my paramilitary 2 has less play with super smooth action ... this is chris reeve we're talking about ... it is in another realm than a pm2 .. 2 other things I noticed on mine are.. if the blade is open and I move it I can feel movement in the pivot screws ... also when I open the blade I can push the lock bar about 50% further . From 25% to 75% ... is all this normal ? Am I just trippin'? .....
 
I have several Umnumzaan's, what you're describing as blade play is not the same thing I consider blade play.
One of mine is tight, if I apply pressure to the blade I can make it move, there is an indetention on my index finger making it move.
The other two, not as much pressure to make it move.
I can make the lock bar over travel also. The movement on the pivot screws are an indication of the tightness or lack of when adjusting the screws. I've got one like that, it's related to the amount of movement the blade has when closed.
I don't have that pivot screw movement on the one that is tight. Of course, it's a little harder to open. I'm wanting to see if it's a matter of break in time or if I need to adjust the tension on the pivot.
So yeah, it's all good and you're tripping
The trade off is, do you want an easy opening knife with easier blade movement when it's closed or do you want a tight opening knife with no blade movement.

I know I'm trippin'.. I had a few drinks , a lot of that was meant tongue in cheek . I also have been experimenting, trying to find that sweet spot . I also tried it torqued a little tighter . But found that I didn't like the harder opening . I hope I'm not giving the wrong impression. None of the things I'm trippin' on has any effect on the overall function of the knife . I am a little more critical of a high dollar knife as opposed to say a paramilitary 2. Also I think coming from the 21 , I expect it to be something it's not . Instead of learning and loving it for its own unique attributes. There are a few knives of mine that I went around and around with at first .and after learning it have become favorites. . It's just my personality I guess .

This thread brings to light that most knives are compared to the Sebenza 21, even the CRK variations. But, being anal about knives comes with the territory of being a knife freak.
I'm convinced the 25 and Umnumzaan make better work knives than the 21, but we all know that's not the case, so based on that, we all have our little quirks that most can't figure out.
 
Try adjusting the screw on the stop pin. The one on my small Insingo will loosen up every so often and the blade will start to drift off center and have a little side to side while closed. Tightening it back up fixes both of these.
