Cuda Maxx 7.0 Framelock

Rat Finkenstein · Jun 21, 2005

I just had posted this in the Blade discussion forum, and they recommended that I post here as well.
I just recently bought a cuda maxx 7.0, and I am wondering if the lock isnt slightly defective. It doesnt seem to move over far enough, even though it has room to go further, and you can push the lock over to where it seems like it should be. The framelock, when engaged, doesnt completely stop the blade from having a small amount of play. it can be heard and felt when wiggling the knife. If I press the lock in, the play disappears.
I will try to post a pic of the lockup tomorrow.

Has anyone had a similar experience with this knife?

Here are the pics of the lock:

Is this a defective lock?
any advice would be appreciated
Thank you

The problem is that the lock wasn't tensioned or bent far enough to engage the blade completely. It doesn't mean the knife is defective in material or workman ship, it was just a miss on QC. It is unlikely that it would unlock on you, but it is a condition you should have corrected. You want the lock to engage correctly when opened.

If you have the tools, you can bend the lock over yourself. It isn't difficult. You also might want to try tightening the pivot a bit. On rare occasions a loose pivot will cause the rattle you describe.

Dirk, Thanks for replying (x2)

I guess I will have to try fixing it myself, But if I fail, will I have voided the warranty by taking it apart and bending the Ti?
I would prefer not having to send it anywhere, as I hate waiting.

Just out of curiosity, does the degree of engagement change with the force of opening? I've noticed that the lockbar travels noticeably farther over on mine when I SNAP it open vice just pulling. Mine doesn't rattle, but there is a difference.

Ok, The main problem with the bladeplay is gone, now that I have bent the lock slightly. Rock solid. Thanks for the advice.

I am still a little concerned about the blade alignment, however. Here is a Pic:

Do any of you have this alignment issue? Is this unusual or par for the course?

Yes it does, although it didnt before. The problem was, the spring wasnt extending far enough when it locked. Now it takes more force to unlock if I snap it versus just swinging it slow.

As far as the centering problem...the method of "bending" the blade toward the side that is going to rub doesn't really bend anything. It just does some minor shifting of tolerances. You can apply quite a bit of force to this. I would start light and increase pressure until it centers. BE EXTREMELY CAREFUL when you do this. I would suggest taping the edge with a few layers of tape at the very least.

Rick, snaping a blade open forcefully versus just rolling the blade out gently can alter where the lock engages. Sometimes a forceful snap opening can basically rebound the blade off the blade stop before the lock completely engages. Thus the lock doesn't quite negage all of the way. Another thing that happens is that the lock might engage further when snapped open forcefully. This can be caused by a few things.

I have seen both scenarios occur in high end custom and high end production. No knife maker or company is truly immune from this.

Thanks, Dirk. I wasn't identifying it as a problem, per se, merely pointing out to the original poster that sometimes if we baby a mechanism it won't perform the way it was designed. An example of that would be gently closing the action on a semi-auto pistol vice letting the spring drive it home. In the first instance, the pistol might fail to go into battery.

Love the knife. Trying hard not to give into temptation and order an Aftermath....

Sorry about that Rick. I misunderstood your post.

Get the Aftermath!
