Sebenza Lock adjustment?

Hello all. I have finally managed to aquire a used classic Sebenza after wanting one for several years. My first cousin first showed me his, which was the first Sebenza I had ever saw or even heard of, several years ago and I have wanted one ever since. He got his back when they didn't even have pocket clips attached and his was a left paw model which was almost unheard of back then. Anyway, my question is this. I seem to remember reading somewhere that the amount of lock / blade engagament can be adjusted by loosening the round spacer which the back of the blade impacts when opened and turning the spacer a little bit meaning the spacer's center hole is drilled of center which controlls the amount blade to lock engagement. Is this correct or am I remembering things wrong about this knife? This is one fantastick knife! I love it! :thumbup: Thanks in advance for the responses.,,,VWB.

PS - I tried to find the answer by using the search function first but it seems to acting up which is pretty common for me.
 
Yes. The spacer on the stop pin can be rotated to adjust for wear (looks just like a different size pivot bushing)... somewhat. From what I gather the stop pin spacer can get slightly deformed from use which can cause a "reset" in lock engagement when rotated a bit. It seems it would work better, obviously, if the pin were made eccentric, but that would come with a whole slew of problems in and of itself.
 
It's been my experience that if there is a lockup issue, it's more likely solved with a taking apart, cleaning, lubing and careful reassembly.

If you haven't done that yet, I would suggest trying that first.
 
How much engagement do you have? :confused:

I'd say unless it's more than 75% don't worry about it.
 
Ok, when I snap the knife open kinda fast the lock bar comes within approx 1/16 of an inch or less of touching the opposite side handle. Is this ok? ,,,VWB.
 
if there's no play it's fine.

1/16 of an inch, when the whole lock bar is like 1/8, is like 50%
 
No there's no play at all but the lock bar looks like it almost touches the bronze bushing on the opposite side. Do you think this is still ok or should I adjust it? ,,,VWB.
 
if you're concerned, send it in. If i's that far over I don't think you can do much.

Did you try taking aprt, cleaning and reassmbly?
 
No but I'm going to tonight. Thanks for the advice guys!,,,VWB.
 
I believe that the blade stop is circular and rotating it probably won't work. I agree with Dave, take it apart, clean and reassemble, it does make a diifference. Snapping the knife open will make the bar go over further and I think it puts unnecessary strees on the pivot. If you are still concerned about it send it to CRK. IIRC, I think that the only problem people have had with the Sebenza lock bar travel is when they do something silly like try to bend it or file it down. If the knife is well used a trip to CRK knife spa would get it cleaned sharpenned and tuned up like new. Then send your sebbie to Tom Krein to get a good edge on it and you will be set to go.:cool::thumbup:;)
 
Well, I disassembled and cleaned it. The lock still travels almost all the way across and almost touches the opposite handle. Does anyone know what kind of turn around time a trip to CRK might take? Man I'm gonna miss it and I've only been carring it for a few days now!,,,VWB.

Just wanted to say that this is not correct. The stop pin is perfectly round. Lock-up can change after re-assembly, but this is just because the very little tolerances and how you've held the knife while assemblying. Also, dropping the knife (closed) can change lockup as well, since it will slightly shift the scales. (Depending which scale hits the floor first and in what direction). Either way, this is all temporarily and after some amount of usage the lock will go back to it's original spot.

Honestly that does not sound like an explanation that takes "extremely low manufacturing tolerances" into account, since every re-assembly should result in the same result unless there were high tolerances or something was deformed.

I never said that the stop pin wasn't perfectly round from the factory, just that it could get deformed over time from usage.

However, my experience has been only from my own Small Classic and the Large Regular passaround so perhaps I am wrong in assuming that the Sebenza's are made with extremely low tolerances and parts can't be misaligned by a simple jarring bump or poor assembly? Just for reference, I re-assemble my Sebenza the way it is shown on the CRK website.
 
Well I shipped it out today to CRK. Does anyone know what kind of turn-around time I might be looking at?,,Thanks,,VWB.
 
Well, just realized you already shipped her out, good luck, CRK will treat you proper!

What DaveH said.

I just had a Sebbie refurbed. I found CRK better than other manufacturers at communicating with its customers. My emails were all answered promptly. CRK people are knowlegable, friendly and professional. I also received a phone call toward the end of the process to ensure that everything I wanted done was accomplished. The knife I received back was in as-new condition.
 
DaveH, how many days were you without it? Start to finish?,,thanks,,,VWB.
 
I also have a sebenza that is about 75% in. I was wondering if maybe they can make a back stopper that is octagonal and and each side is slightly, and I mean very slightly, higher that the next to account for wear and to adjust for by turning to were the lock-up is just right.
 
I dont know but it sounds like a great idea to me! maybe you should give crk a call and make the suggestion to them!,,,VWB.
