No I mean the blade stop. The little piece that stops the blade in the closed position. its on the spine right behind the blade when opened.
Oh, nope. It's not wiggling or anything. Sound must be coming from the KVT.
I just got my 0561 in today and I'm having the exact same problem. I've dealt with a couple different frame locks, and this one is stupid hard to disengage. It actually hurts my thumb to do so. I too don't want to take mine apart, because I'm not a "tinkerer" and would prob not put it back together the exact same way. I'm thinking about just putting it up for sale, but I still want to give it a chance. The blade flips out just fine, and I can open with thumb stud just fine, but closing the knife is just torture.
Well, I purchased a bunch of sharpies to try to see if it solves anything.
