112 Slim Pro TRX sucked until I voided the warranty.

I am going to forgive and forget and hope you will to. Let’s put flicking my knife open aside for a few minutes. The 112 Slim Pro TRX comes with thumb studs. It was designed to be opened using them. My knife had so much tension it was extremely hard to open, I,m not going to say to the point of being painful, but it definitely wasn’t easy. Then when it gets partially open it gets to that shoulder and gets really stiff and binds up. At this point I can no longer push it open and have to reposition my thumb and push again or use 2 hands to finish opening the knife. This is why I said it sucked, because it certainly wasn’t a one step smooth motion like it should be.

I joined the Navy in 1972, I was stationed on a destroyer escort out of Pearl Harbor after boot camp, and that is where I saw my first buck 110, almost every sailor had one. When you get there they usually have you teamed up with someone who has been in awhile so you learn how to do things. One day I saw the guy I was working with take out his 110, clasp it between his thumb and fore finger with the pivot pointing towards his elbow, he then swung his arm outward and flicked his wrist and the knife snapped open. I was pretty impressed. He showed me how to do it and I have been able to open every 110 (4 of them) and 112 (2 of them) I’ve had that way since then. So I was kind disappointed that this one wouldn’t even start to open that way. By the way that was pretty much the way everyone I was stationed with opened their 110‘s.

What luck to land a Pearl Harbor assignment right out of boot camp! I'm out here now and enjoying every second of it - my blades and bike not so much as we wage a desperate fight against the corrosion.

I had something real similar with this guy here:

It showed up tight but fine, I put a thumb stud on it and some on the pivot and fooled around with it for a day or so and put it away.
The next time I used it the knife would open up about 3/4 of the way and then bind.
Cleaning, oil, nothing would fix it so I sent it back to Buck.
It came back with a packing slip stating "Spa Treatment" and it was fine, I put the thumb stud back on, some oil and it was fine for a day.
The following day it was binding in both directions! It wouldn't even close.
More cleaning, nope. More oil, nope so back it went.

Buck's warranty department called me up and said it's fine, it snaps open and shut just like it's supposed to.
I told them that it would be fine, I'd put it away and the next time it would be binding.
We both agreed that's weird and the young lady said she'd clean the bolsters and oil it.

I have no idea what they did but it came back with some free play in the blade (only in the closed position) and it's just perfect.
I wrote to them and said PERFECT! but I don't know if they read the email but they did a great job.

The black stuff on the spring is some tungsten disulfide I'd mixed with 0 weight synthetic oil, there's less of it on there now.
