sebenza w/ sticky lock disengagement?

I once had a small classic in which the lock would randomly stick soo bad it would take two hands to unlock it, it smoothed out over time though.
 
I had a knife like this and happened to have it in my pocket at a Blade show, so I showed it to the Reeve people and they took it back with them to figure out the problem.

Turns out that there was galling between the blade and lock bar due to a poor heat treat on the lock bar.

The knife was fixed, totally refurbished and sent back to me. That was three years ago and the knife is still fine.

I'm sure they will take care of you too :thumbup:

i guess it's possible your issue required more time to fix. Who knows? as it turns out my sticky lock issue doesn't seem to be terribly complicated.

I'm sure they'll take care of me too. i think your problem was exactly the same as mine, in fact Heather told me they had to re-heat treat the lock bar.

This is what happened to my first sebenza, a small cgg. Here are some pictures that I took and sent to CRK. It happened a few years back and the sebenza was gone for about a week. They mentioned that they had to sand it down as best as they could and reheat treat it. I used it for another 6 months and retired that sebenza due to sentimental value. I open it every month or so when I take it out of the safe and oggle it. :thumbup:

I have used a small dot of CRK Fourinated Grease on the lock face of the blade.
It worked well and did not affect the security of the lock.
 
graphite and oil will only hide the stickiness, it's not a permanent solution. Best to send it back. Having handled about 5 large regulars, 3 of them were a little sticky (but not sticky like say an emerson) and after a couple hundred opening and closings, they became smoother. I hear that having a carbidized lockface helps (like in mayos, hinderers).

of course not as smooth as an umnumzaan, but the umnumzaan has a ceramicball in place of a ti lockface.
 
Well i got the knife back yesterday and it was kind of bittersweet. I never really mentioned that as time went on, i started to get a little bit concerned about how far the lock was engaging. I would say that on occasion the lock would travel almost 85% of the tang. This is no longer a problem, however the sticky disengagement is pretty much exactly as it was before i sent it. So i guess it can't be fixed, i'm kind of disappointed.

On a good note though, they re-blast the handles and installed the perforated washers. The knife is smoother than it's ever been, and it looks pretty much brand new. They also, cleaned and sharpened it.

here are some pics side by side with my plain edge Lg Reg. Sorry they are only cell phone pics. I'm too lazy to use the real camera at the moment.

If the lock bar and Blade tang do not look like the one krazichinaman posted or resemble the same then the knife has no major problem. The thing is Ti is sticky for some time, liner locks out of Ti do the same for a while and then they smooth out. Some makers prefer the stickiness as they feel it ads in safety and prevents accidental lock disengagement. Of course if the knife just got back from CRK and the lock has some stickiness it is in spec. No Sebenza should take two hands to disengage the lock of course, that amount of stickiness I do not think CRK would agree with.

You have the CRK serrations that are now standard. I do not know chadridv was a after market job or earlier Sebenza, do think it is after market but sure he will chime in.
 
Hey sorry to take so long to respond, i didn't see your post until today. The serrations are definitely not after market. It came from CRK, and it is marked accordingly on the birth card.

As for the sticky lock, i suppose it's really not that big a deal, and as you mentioned some makers and users actually prefer it, as it does add that little bit of extra protection from unintentional disengagement.

Although, my knife is not so bad you need 2 hands to disengage it, it is bad enough to be annoying (IMO). The worst part is that it still has more or less the same exact problem. I was kind of under the impression that CRK fixed it, but i guess they didn't.

I have found that mine are least sticky when absolutely dry. It's easy to get oil on the tang ramp or lockbar face. Even grease (which I prefer for Sebs) can migrate there. Just a thought, with hopes that you can solve the problem.
