Umnumzaan lockup question

[Norcaldude]

I recently acquired an older Umnumzaan, 2009 with the pivot that needs a special tool to open. I really like the knife and it works just fine but the lockup goes pretty much to 100% and I'm wondering if it's something I should worry about? Here is a picture of it:

Close it and look at the tang. The ceramic ball lock up will be different than bar. Even with that said the trail sometimes goes across the entire tang. As per email with crk.

I'm sorry, I don't understand what you are saying here.

From CRK, unless the lock bar is touching the other side, then you are good to go. They prefer 70 percent lock up, and if its more, in their opinion it provides a more secure fitting.

The lock on an Umnumzaan is not like a traditional framelock. Instead of the titanium touching the tang, there is a large ceramic detent ball fitted into the titanium, and that is what contacts the tang. If you consider the lockup to be where the contact point is, your knife has a lockup of 60-70%.

Some of the pictures here of the lockbar very clearly show how the lockup works (and it is a bit hard to explain).

Basically, what he's saying is your knife is fine. Go back to using it without worry. :thumbup:
