Rocky Relationship With My New Umnum. . .

Hello my CRK brothers and sisters. . . I want to give a shout out to my man Kinagoo (Alex) for the great transaction on his gently used Umnumzaan. I purchased it from him a week or so ago and have spent some time getting to know it. Despite his funny screen name, Alex is a good man--don't hesitate to deal with him!

My new (to me) Umnum came to me in great condition--she was sharp and had very few scratches, mars, or dings on the Ti or on the blade. I put her in my pocket and went on my way. I am used to carrying a small Regular Sebenza, but despite its much larger size the Umnum carries slim and quietly in my pocket. I spent a little time getting used to the different opening method required on this beast and after some sore fingers I am starting to effectively open her up.

As is my usual M.O with a new CRK I like to break them down, inspect them, clean them, and get to know them in general--let's call it "bonding time." No room to tease me about bonding with an inanimate object, I know you CRK freaks do the same thing--even if you won't admit it. So, before I started to break her down I noticed that the blade was a tad off-center--not rubbing liners, but enough to clearly see it with the naked eye. I know the pivot sometimes needs to be adjusted to correct this so I was unphased. I began the dismantling process and was a little put off by the two size of hex keys--it is so simple on the Seb's to have one tool needed! No biggie--I put on my big-boy pants and got to work. I tore her down and she resisted a little, but I eventually got her dismantled, inspected, cleaned, lubed, and began the re-assembly. The level of difficulty exceeded that of the Seb's I have been used to, but I am sure there is a learning curve. After some struggle, a few drops of blood, a few beads of sweat, and some mild expletives, she was reassembled.

I then re-inspected her for ease of opening, centering, etc. She was still off-center. So I adjusted the pivot until she was centered. Too stiff to even open. Readjusted the pivot a little, she can now open with some force, but is a tiny bit off-center. Re-adjusted tighter--closer to center, harder to open. And so on we went with adjusting, readjusting, etc. I cannot find the "sweet spot" as some have called it. The utopian spot where wine flows from the rivers and angels tears water the gardens--the spot where she is centered and still opens easily. I had an open discussion with her about the need to be "centered" in life. We discussed the idea of her being centered AND easy to open. She refused. So, I quietly wrapped her in her CRK cloth, put her back in her box, and spent the next hour or so weeping gently over my now tainted relationship with her.

For those Umnum users--any suggestions, tips, tricks, or other mechanical or psychological steps I can take to reason with her?
 
I have no suggestions, tips or tricks, but I sure enjoyed the read!
Hopefully someone here will chime in with just the right advice.
 
what worked for me was to overtighten the pivot to make the part on the locking side to really settle becouse after i broke her down the pivot dident wanna go all the way in, after doing that i really only need 1 hex key for the pivot its pretty snug in there,
 
ZCD--"Shim" it? That's a negative sir. Explain please.

You can use several sheets of paper to "shim" the blade towards center, loosen the pivot and body screws as required, insert the shims next to the pivot, tighten down to "shim" the blade towards center. Loosen it off, remove the shims and re-tighten - repeat if necessary. Hopefully that helps!
 
I bend em over my knee when they refuse to listen...
Or you can try the takedown method everyone else uses. I've never had centering issues with my Seb but there are probably videos on YouTube about it. It has something to do with barely releasing the pivot and removing the standoffs in some particular order and then reassembling it...or something like that.
 
Thanks for the input so far folks. . .
Hmmm. . . The Umnum seems to be a finicky little gal. She is more of a "Shrimp Salad and White Wine" type of gal. The Seb is more of a "Burgers and Fries" type of woman. . . Pros and cons to both I suppose.

Except when it's time to do some work, then she smashes the wine glass over someone's head and kicks them when they're down.

The Zaan is one hell of a knife, I am thoroughly impressed with my recently acquired one.
 
I dont know why so many people have problems with this knife. Its the most simple knife I have ever owned.
 
I just got my first Zaan two days ago and love it so far. But I'm having the same problem. The blade is favoring the none locking side just a bit. If i try to tighten the pivot just a c-hair the blade wont open. I think I'm just going to give it some more break in time before i screw with it anymore.
 
Funny post, what if you were to try assembling the knife with the pivot screws switched around, worth a try maybe.
 
Maybe flip the washers. It's worked for better adjustment for me in the past. Turn them over is what I mean.

Thanks gents... I will try both of these ideas.
I'm wondering if maybe I need to let it just break in a bit. I am not the kind to open/close/open/close et al whilst I waste away watching the boob toob, but maybe I give that a try too? Any good shows on tonight? I watched my Jazz dismantle the Heat last night--I should have done it then!

I understand your pain but I definitly dont agree that the zaan is "finicky" at all. Takes me literally less than 3 minutes to take it apart and put back together. Both my zaans have blades that are centered even with the male pivot screw out of the female pivot screw completely. This might sound odd but make sure you properly lubed up all the moving parts when you take the zaan apart. CRK grease is highly recommended when doing so. I feel like Mr. Reeve designed both the Sebenza and Umnumzaan to be used with a high performance grease to help make sure everything is nice and tight.
 
Loosen all the screws then shove a folded up piece of paper between the blade and the non-lock side so the blade is pushed up against the lock side. Now bang the back of the knife a few times on a magazine on a table. You are trying to get the pivot to adjust just a micron. Now tighten up the pivot screw until it won't tighten anymore. Don't crank it, just get it to where it won't tighten anymore. Now give it a couple more bangs on the table for good measure. Now tighten up the handles screws all the way. Now, remove the paper wedge. The blade should be off center to the lock-side. Now loosen very carefully in tiny amounts until the blade moves smoothly as you like it. Hopefully the blade is now centered.
 
Thanks for the additional responses and suggestions--much appreciated.
I had an epiphany... Maybe I am just being insecure in my relationship with her? What if it is ME that is off-center and behaving like a clod? Self-reflection is a must to any healthy relationship. I just took these pictures--am I loco? Is this blade centered? In this current position it is still fairly stiff to open--I can't thumb flick it open, but if it is currently centered then it may just need some time to work in. I know angles can be deceiving, but what say YOU? Is it the blade thats off center? Or, is it ME that is "off?"

Those pictures look pretty centered to me! I look more at the gap between the blade and the the 2 handles to determine if my blade is centered. But for me, just going by the tip location, I'd be good with that!
