Interesting Lockup Change

Folks,


I disassembled my small plain Jane 21 for cleaning/lubricating and upon reassembly I noticed a change in the lockup percentage. I disassembled again and reassembled to see if it would change back and it remained at the new lockup percentage. Odd? I have cycled it repeatedly and it stays the same. I have applied pressure to the spine to see if it would slip and it does not slip closed, although the pressure applied wasn't that great. Any thoughts?

Lockup Before at Appx. 50%:


Lockup After at Appx. 25%:
 
I no longer notice my lock-ups or even care. If they lock, that is good enough for me. I mean, has anyone actually heard of a lock failing due to late or early lock-up?

But I used to care and therefore sympathize with you. :)
 
Do you do the light one time flick open that CRK suggests right after reassembly?

Yes. I pretty much follow their instructions to a T.

I am not really concerned that this is an issue--I am more just interested in finding out if others have had this same experience.

I've noticed that if the stop pin screw is loose then it will cause it to have later lock-up, maybe it was loose before you disassembled it.

If it were say, 10% lockup I would be concerned, but 25% seems like it is locked down pretty good.

Thanks for used to caring--I feel loved!
 
I have observed this change several different times. I have yet to see a pattern, sometimes the lockup changes and sometimes it does not:confused:
However, the lockup always stays rock solid!
 
I wouldn't worry about it, though it's never happened to one of mine.

I have a large insingo that has approx a 20% lock up, thought that it was perfect as it'd take three lifetimes to wear it out. Then my buddy came over and said that he'd be worried about it being to shallow, that it may slip, I laughed it off and decided to tap the spine lightly on my table to prove him wrong- it popped on the fourth tap- no biggie, it's a bs test and I don't use a knife that way, so I forgot about it. Then a few days later while using my knife IMPROPERLY! ( at a party and some brownies had fused with their pan on a molecular level, had to save the day ) I was using the curve on the swedge of the spine of the insingo so I didn't mess up the pan, pressing it in between the treats and the pan, and it popped. Blade bit me pretty good but it was my fault, the knife was unhurt, and the brownies were worth it so no harm done :)
Completely my fault but if had a 40% or better lock up I don't believe it would've slipped.
I like it how it is but if I ever come across stuck brownies again I'll go back inside and get the right tool. For any other normal use it's fine.
 
Interesting. I watch your videos, they're a big reason for why I'm trading my 25 for an Insingo. I'll have to check the lock when I get one! :)
 
I've seen this with pretty much every Sebenza Ive had & taken apart (around ten). I figure it is because the stop pin sleeve gets minutely flattened where it contacts the blade tang & it gets rotated upon dis/re-assembly effectively adding more material there and causing the lock to contact earlier. Dunno though. Just a guess.
 
Well I truly do appreciate the support, as always.
Please don't take that one experience as any bad info on a Seb, CRK's frame lock is one of the absolute best on the market.
This one Insingo is just an anomaly, kinda like the occasional off center Seb that you read about, I'm sure that its why I'm the third owner of it as it probably worried the first two people.
I love it though, it's rock solid, and if I hadn't have been using it like a fool it wouldn't have bit me. It's alright though, the Insingo's get so crazy sharp that I didn't even feel it ;D
Plus it gave me an excuse to wear one of the kids Phineas and Ferb band aids which is always cool.

With how you love CRK's you need an Insingo, personally, I can't wait for the fabled Damascus version to finally be produced.
 
Every CRK I've purchased new had this happen. Usually they come to me from the factory around 75% lockup. I use it for a few weeks then clean it and it always goes back to about 50% and stays there for as long as I have it. Even after multiple cleanings, it always stays at 50%.

I agree that it may have something to do with the stop pin sleeve being rotated after wear.
