Hello all,
Help! I need to tighten the pivot on my Umnumzaaan I just received in a trade. Any ideas.............. BTW I already tried the drill bit method, it seems to be frozen.
 
I've seen one out of six Umnum's I've handled that has had lock tite applied to the threads of the main pivot. Which means you either have to apply direct heat to the pivot with a soldering tip, or have two take down tools and counter rotate to break the lock tite.
 
I drilled a small piece of corian, (wood would work to, my pivot wasn't too tight but there was thread locker on it.) and put two small pieces of brazing rod in the holes just long enough to fit into the pivot and superglued them in. Easy enough to make two of them, one for each side. The brazing rod won't scratch the pivot if it slips. It works OK if you need it right now.

The Boker RBB has a similar style pivot, and comes with a tool.

Not sure on the diameter though

Good luck

:)
 
I just checked my golf spike wrench, nope, but close, good idea though.
 
Sure I'll send it to you, but first...... send me a custom Ken or Alsdorf slippie! Preferably a bone or stag handle one.
 
But how is a combo of blue Loc-Tite needing to be heated, the need of a special pivot assembly/disassebly tool, and the lack of a bushing an improvement over the Sebenza?

Just curious to know, and would especially like to hear from those who tout the Unum as a more refined knife than the Sebenza.

I still think they're apples and oranges in comparison, and as someone who uses my Seb's regulary for often nasty chores, I like the ability to take them apart without hassle. The "refinement" comments also escape me.

Not trying to flame, just want some Unum owners/users to educate a long-time Seb owner/user. Thanks in advance.

It might be a good idea to start your own thread instead of hijacking this one.

It's not really that off topic. I really only expected you to reply anyway, so why not do it here?

Maybe could save some bandwidth that way!

:D

Different does not equate to better. And I'll stop there, as I no longer have access to the appropriate forum.
 
I didn't have to heat mine to get it apart. Only one pivot and one screw holding it together, Sebenza has three. Thicker blade. Just a different knife.
 
Someone should replace the pivot assembly with one that you can take apart with conventional tools,

I take my knives apart and / or adjust the pivot about three times. This includes any brand I buy.

The first time occurs shortly after purchase. Everything starts breaking in and I usually need to tighten the pivot a bit. This occurs on every knife I have ever bought.

The second time I do it is after the break in period. The washers and blade have had time to polish each other. I strip the knife down and clean the original lube and any break-in deposits from the pivot area. I can get the optimum adjustment in a few tries, (it isn’t rocket science), after this, and then I’m good to go, for years usually.

If I don’t drop the knife in salt water or bathe it in blood after skinning something, I can go for a long time without ever needing to open the knife up, otherwise, this would be the next time I would deep clean a knife. Since I use fixed blades when skinning, blood isn’t even an issue for me.

I have NEVER needed to adjust or disassemble a folder in the field.

So my question is: what’s the big deal with needing a special tool for a pivot?

As far as the magical pivot bushing goes, my zann is as smooth as any seb I’ve ever used. There is no blade play at all. I guess Chris figured it out.

I do think there are several refinements made to the zann.

The ceramic ball in the lock area is a major step forward. The lock NEVER sticks.
For this reason alone I believe the zann to be the best framelock made today, regardless of manufacturer.

The nail nick on the framelock bar is another great idea. It works so much better than the ridged jimping found on virtually all other framelock bars. Why didn’t someone think of this before? Thanks Chris.

The handle is more ergonomic on the zann than a seb and has better grip due to the cross-hatching.

The blade has a swedge. I don’t have to dull my edge scraping fire sticks, or anything else. No wonder CRK got special order requests for this feature on sebs.

The blades two ramp detents are a very nice addition. I’d rather have them than not.

Alas, one cannot get mammoth tooth or wood inserts on a zann, so, maybe you’re right.
Maybe the zann isn’t more refined than a seb.
 
Nah, I don't think I've given the Unum a fair shake to be honest. I said it myself, it is a different knife, and comparisons are like apples-oranges, thus I need to try and appreciate the Unum for the different knife it is.

The other thing is, you're on the money with Chris' vision. He put somewhere around 20 years into the development and refinement of the Sebenza, so I think in regard to their products, the best is yet to come.

Heck, we'll likely be looking back in 10 years thinking "S30V, ick!"

Caps and two e-points? Seriously? Are you really that upset or offended by a good-natured post on a knife forum? He wasn't even that off-topic. Besides, isn't that a job for moderators? Please don't take offence to this, as I don't mean it that way at all. I'm just amazed at how aggitated some get on this forum over what are ultimately harmless mistakes.
