Is there any reason to adjust or disassemble my Umnumzaan? If so do I need a special tool?

thanks
 
The tool made for the umnumzaan makes it easier. Before I bought the tool, I used 2 round toothpicks with the sharp points cut off down to where they fit the zaans blade holes the best......... Is there any reason to take the zaan apart, not really. I have had mine a couple years now and and never took it apart. I took my tanto zaan apart for cleaning as it was used when I bought it. Any new zaan though should last years without re-lubing............ As for adjusting, you don't really have to adjust it either. CRK uses the purple loc-tite which holds the blade pivot bushing in place an it will not lose adjustment due to that.
Its a great knife throughout.
 
I only take the knife apart for cleaning and that is probably only every couple of months at best. I spend a lot of time in a work shop where all sorts of dust and bits of bad things are ready to jump in my pockets and all over my knife. For normal pocket use I can see the knife lasting a long time before really needing cleaned. Even just washing it with water with out taking it to bits is enough to get rid of most things like fruit juice, sand or mud.
As mentioned if one uses loc-tite on the pivot then adjustment over time is a virtual non issue. I have actually had few problems even when not using loc-tite. The special tool isn't needed, but it's inexpensive and definitely makes life a little easier when it does come to beaking the knife down for cleaning and relubricating. For about $12 you get two tools, two hex keys and a tube of purple loc-tite. That kit will probably have most people covered for ever. :):thumbup:
 
I used the startac a lot and the pivot can come loose after a while. Usually just tighten it up with my thumb, though a quick application of loc-tite would have helped.
 
I just bought an umnumzaan tanto second hand. Took it apart last night and the lube is gone on the brass washers (correct part name?). The lube is gummed and right on the outside circumference of them. It's amazing how smooth the knife functioned with the lube the way it is. I will be calling tomorrow to order some. I'm curious to see the function after a lube job.

I wouldn't take the knife apart unless cleaning or adjustment is needed. Then use the Loc-Tite. I didn't use the Loc-Tite and reassembled the knife. After a few openings the pivot loosened and the blade was touching the side. I don't plan on carrying the knife until I get it lubed properly, that's why I didn't use Loc-Tite on reassembly.
 
Oh and I don't know if it comes standard but my disassembly kit included with the knife came with the Loc-Tite. Like I mentioned above it was purchased second hand.
 
The tool comes with a small tube of purple LocTite, but the Umnumzaan doesn't come with the tool - it's a separate purchase (around $12).
 
I just use the pad of my thumbs to uncsrew the pivot... but ive got calloused guitar player thumbs, so YMMV.

As far as putting it back together, I find putting all the parts on the locking side scale then putting on the flat scale and screwing everything down.

As for the pivot, I tighten as much as possible with thumb, then back off a little bit so not too tight.
 
As a verbal report, that doesn't necessarily sound bad. You don't need, or want, lube everywhere. An extremely fine film is all that's needed. The perforations in the washers will retain some lube and keep things moving smoothly. However, I haven't seen what you've seen in person, so it may need re-lubing.

Definitely use the LocTite when you re-assemble. :)

Will do. I was going by the lube. It's more of a gum consistency mixed with gunk and lint. I didn't order any lube, maybe I'll have time tomorrow.
 
The new tubes are sort of small, consider ordering two? :) I use the CRK lube now on most of my framelock and several of my linerlock knives. It's great stuff and, among other things, attracts less gunk and lint than most lubes I've used.

Why don't they sell it in the syringe anymore? Seems you would have better control in your application.
 
There was a post from Ann, Heather or someone else from CRK on that a while back. The short answer, IIRC, is that they are no longer commercially available. I have a few old ones and recently refilled one of them from the tube (worked fine).

Edit here's one post on this:

We all loved the syringe but CRK’s vendor could no longer source them -not sure why. We waited for about a month to see if the situation would change (you may have noticed a lube shortage a bit ago) but it didn’t. In order to supply grease to customers we were forced to go with the tube. I’ve no idea if the syringe will come back but we would like it to. Just a note, the quantity is the same. It is just the container that has changed.

My dad got a case of syringes with needles a few years ago from somewhere. I'll have to get few from him.
 
I would love to have the syringe, but i usually just put a drop on a part of the washer, and then use a toothpick to spread it around and into the holes of the washers. (I'm sure this is a common sense application that most use):)

Ok, who has an extra syringe??
