I've carried one for about a month and I think the design is brilliant. The ergonomics are better than the Sebenza. I'm impressed.

However, I cannot open the knife left handed. My left thumb slides over the smooth low stud's rounded button head. I suggest the left opening stud be increased in length by about 1/16 of an inch.
 
I think both the thumb studs could be grippier. I also think the top edge of the cutout for the framelock is sharp and should be rounded off smooth like the rest of the edges. I have not found a perfect folder yet, but this one is pretty close.:thumbup:
 
I don't think Chris ever designed his knives to be flicked. Obviously you can have any argument you want about flicking a knife, bottom line is flicking causes wear and stress. Plus who flicks open a gentleman's folder?

I agree on both
 
don't flick your knife! but when you do anyway; Chris plans for it (to some extent) when he designs a knife, and tries to make a tool strong enough to endure your . . . enthusiasm. also; i believe both left and right hand versions of the umnumzaan can be purchased.
 
Flick as in a single, fast and forward push of the thumbstud to deploy the blade, not a wrist flick. Is that frowned upon even? I can't help it, fast opening knives just feel natural to me...
 
yea Im with you Adamlau, I dont wrist flick but I do like to open the knife with one push of the thumb and maybe a little gravity:o I didn't spend $400 on a knife to not enjoy it. plus, I find it hard to believe that flicking this knife can somehow damage it, worst it could do is wear out the ceramic ball a little faster than normal and guess what..the ceramic ball can be replaced with a new one!:p

It's kind of like doing burn-outs at traffic lights. Some of us are happy to have moved on from junior high... but I guess we all want to break traction now and again - just not all the time, eh?
 
I'm reviving this thread because I got a Zaan for Christmas from my wife and agree with roshi. The thumb studs are too short and too smooth. Opening with the right hand is ok until you put on nomex gloves and it becomes difficult. Left handed opening is out of the question all together.

Hopefully, CRK or someone else will offer new thumb studs soon or i'm going to have to recontour and serrate the domed ones for better traction.

If CRK wants to do better in the "tactical" folder market they're going to have to consider those people who go to work with gloves on.

stop trying to open things with the wrong hand.

What wrong hand? I can open and close any of my framelocks with either hand. :)

Finger flicking it open is fine. A heavy wrist flick, slamming the blade open, is a bit more destructive. I think the bumpers on the Umnumzaan buffer even for that.
 
I read all these complaints about the umnum and I'm just amazed what folks come up with....the thumb stud works just fine for me as does the lock bar and everything else about the knife...IMO, i also believe that this knife has greatly surpassed the sebenza in every way....and I'm appalled at this talk about flicking the knife...i believe that this knife will stand up against any daily tasks presented within reason.

As far as left handed use...it is designed for right handed use....most southpaws that can walk and chew bubble gum usually learn to manipulate a right handed knife or get one made for left handed use.

As far as gloves are concerned....most frame locks don't fair well with glove use.
 
I think burnouts are way cooler as a grownup. (probly cause I don't drive my parents stationwagon now though):D

You can always do what I'm going to do, wait for the left handed one to come out!:eek::cool::thumbup:
 
I agree with Roshi. IMO the handle ergonomics is better than the Sebenza but the "wrong hand" opening is quite difficult with the Umnumzaan. BTW using the glass breaker must be quite hazardous for your fingers due to the (useless ?) skightly sharpened back edge.
