Any tips on centring the blade on a 0560?

Blade centering on the 0560 is odd to work with. The usual methods don't work primarily due to the bearing setup. You could try different washers, I've had that work sometimes. If it's only slightly off, I recommend leaving it alone.
The lock stick will eventually go away. More pencil will continue to alleviate it, and work better in doing so as time goes on.

Can't help on the off center issue but try permanent marker on the locking surfaces. My 0200 was so bad my thumb was raw and I would need both hands to unlock. Try the marker trick and let dry, then work the hell out of the it. Give it time, it will improve.

Thanks for the feedback, the knife has been smooth from the box, once past the detent ball smoothing a path over the BB tang it flipped open and closed flawlessly and smoothly.
Over the last two weeks the lockup has shifted about from 30% to 50% and developed the sticky lock, the blade has also moved further off from centre, I suspect this one needs to go back to base.
There were no loose screws causing this, I have of course loosened them all up trying to centre the blade, I've also flipped the ball bearing over to see if it that had any effect, of course it didn't.
I've edc'ed this for 5-6 weeks and overall its a great knife, looks like the XM may get a chance at EDC while this is away.

That's unfortunate. I didn't extensively use mine, it's a show piece now that Rick signed it and Thomas put a black clip on it for me. So, my experience is limited to the regular 0560 models. I have a pack of the KVT washers, and switching the out eventually netted me a more centered blade. They'll likely have the right setup for you. Cheers.

Did this happen after you took the knife apart and reassembled it? Sometimes I've found that if you reassemble a knife and accidentally flip the washers over, or swap sides, that can affect centering. I've never had it happen with KVT though. Could give it a try. I *think* the bearing rings are the same on either side. I had a sticky 0560 and it eventually smoothed out.

Yeah, I agree with Moxy. The only time I couldn't center mine by just adjusting the pivot screw was if something got put back together wrong. In some cases it was the blade stop pin. Other times something else didn't properly snap-to. Take it apart, clean, put back together carefully, then see if the centering problem persists.

The blade centring was an issue before I first took the knife apart.
I've since taken it apart again and reassembled with all bearing configurations possible, none make a difference.
What I did notice is excessive wear to the Ti lock side bearing recess, the steel ball bearings are wearing a channel into the Ti, it is not uniform wear. There is also wear to the tang on both sides and the steel liner. The Ti lock side bears the heaviest wear.
The detent ball also has a worn flat spot and a corresponding groove worn into the tang.
This knife, at 6 weeks old bears more wear than my main EDC Hinderer XM which I have flipped the bejesus out of for 18 months prior to EDC'ing the 0560.

That is interesting to note.
I had a Kershaw with KVT that I could not get to center up, but I did not notice any unusual wear patterns (maybe I did not know what to look for...).
I decided it was not worth sending it in to ask if it could be corrected, in my situation. The knife has been fine in use, and it has seen quite a bit of use.
For a beautiful knife like your 560CBCF, I would want it to be well centered.
Please let us know how your experience turns out.
best regards

That's really concerning. I never noticed had that problem with either of my 0560s. I would suspect that dirt/debris, and other small abrasives, worked their way in an slowly eroded away at the titanium via the grinding action of the bearings. Titanium has a rockwell in the 40s at best, I think. So I'm not surprised it would wear away before the bearings.
Call KAI and explain the situation. I'm sure they'll help you out.

I don't believe that a soft 440 steel bearing is significantly wearing channels into the titanium, the hardened Elmax blade, and the liner. What you're seeing is likely a bit of polishing of the surfaces, or as was said, some kind of abrasive contamination in the race area. The detent ball bearing a flat spot is normal, and it happens to all knives. If the detent functions, it's not an issue.
The detent ball flattened on all three XM-18s I've had. All of them. I also noticed the same thing at Blade Show when I asked to see the XMs of several USN folk. If you're not seeing that kind of wear on yours then it's unlikely that your XM is as used as purported.
If the centering is bad enough to impede the function, then send it back for repair.
By the way, it's "centering." Cheers.

Actually it is centring, you see I'm using the English language not Anglo slang.
And, as for the insinuation of lying over my main XM usage, I can give the member names of several forum members who can vouch that I have EDC'ed one particular XM for about 18 months. To add, that particular XM was my first Hinderer and it did not come to me in new condition, it had very clear usage marks.
The detent ball on that particular XM is not as worn as my 6 week old 0560CFCB, these are facts despite whether you choose to believe them or not.

Do you always have to respond with such a snappy know-it-all attitude? Stop making personal assumptions about irrelevancies. If Jay says the bearings are not wearing uniformly in the Ti side then who are you to say otherwise? I'm sure he can tell the difference from a "bit of polishing". And they're not "soft" bearings. Typically they're 440c and around 60 Rockwell.
