Is this a lockup that still has some life in it, or is imminent for a factory re-do? (see pic)
I just this weekend noticed this( it has always been about 50% till now). It has NEVER been any further over than this.

I seem to recall previous threads mentioning that up to 75% coverage is still within factory specs. If that's the case, your still fine.

P.S. Can anybody confirm this 75% figure for me?
 
Once it moves over it can be fine and dandy for years to come before it needs attention. No worries at all. Its just that much closer to a fixed blade.

Thanks STR your word is bond.

CRK says in their facts, that PAST 75% one should contact them. Mine is "almost" there.(my reason for asking)
 
If that pic is your current lock up you have a long life left on that one. 65 to 75% is a great lock up and I'd prefer that over 25 to 50% personally.

I did ask CRK about the same lockup and 75% is normal for them. I also prefer at least 25% myself.
 
I just had a look at mine, (its about 3 years old), and its a little further over than yours. First time I've ever really looked at it.

What would be the problem if it went all the way over?

I've been thinking this same thing since I saw this thread, and I think it must be because it is not technically "locking" into place at that point and must have some blade play because of it. Doesn't seem like it would be more likely to fail though. Of course I am probably wrong... What does CRK do at this point, replace the blade? I'd hate to loose my BG42 blades to this at some point.

I seem to remember from the CR video the spec range is 20 --> 60%.
 
I wouldnt worry about regressing...this is after hundreds of thousands of flicks (sorry about the pic being crapp, old cell phone)

I need to measure mine at work tomorrow, but if I have a brand spanking new Sebenza bought from a brick and mortar CRK dealer this weekend and the lock is already at 75%, should I send it in?
 
My current edc Sebbie is about 3-4 years old. It settled in at or around 75%. Some of my older ones 7+ years settled in at 60% have have never moved since. I've found that each Sebenza (because it is hand tweaked) each take on a life of their own. Once they break in over a good period of time, they tend to settle into their "sweet spot". I wouldn't worry too much about your lock up. It is a great piece of engineering. We all know that or we wouldn't be here:)
 
If it ain't broke, don't fix it!

You could always follow the suggestion of disassembling/reassembling and see if it "resets" your sweet spot some.

I realized lately that if the pivot screw is not tightened entirely, the lock coverage will be greater. When my relatively new sebbie is fully tightened, the coverage is about 40%, but if it's slightly loose (as tends to happen during use, since I don't use lock-tite) the coverage is between 60% and 90%. That's probably a factor for a few folks, since it isn't easy notice.
 
Your pivot screw or any other screw for that matter should never be loose. I would suggest going ahead and putting some spunk behind the allen wrench when tightening them down.

As was once said here, your Sebenza screws should be tight to the extent that they "pop" when you loosen them to disassemble. The 303 stainless screw and receiver should slightly gall when tightened.

Prof.---Good advice>don't muck with it!! And gull wing--- since yer done worry'n about yer Sebbie lock-up, you can concentrate on make'n more Sebbie handle slabs for us!
 
I found on the passaround Sebenza that one screw kept working itself loose and wouldn't tighten down properly. The lock traveled all the way when you gripped the knife hard. Said to myself, something's not right. Took it apart, cleaned it and put it back together, now it works like a brand new knife, with about 1/3 engagement of the lock.
