How long before it scrapes the liners?

Got my BM-730 like two days ago. The blade centered perfectly, but I noticed when I opened it with the thumbstud (involving a little pushing to the side to get a grip on the stud), the blade comes close to rubbing the liners. How long before it actually does rub the liners? And is this covered by the Benchmade warranty? Could I ask them to replace the washers if the blade started to wobble too much even with pivot tightening?

make sure this isn't just an optical illusion. See if the spacing is any different than the thickness of the washer. If it is closer than that distance, there is definitely something wrong, and you should return it, but I have a feeling that it's just close, but not getting any closer.

One question: why are you pushing hard on the thumbstud? This is an Axis lock. If it is not smooth as silk, it must be tightened down way too much.

My instruction for adjusting the pivot tension on an Axis lock:

Loosen the pivot, then hold the knife horizontally, open-side-down, then retract the lock. The blade should swing out. Tighten a little at a time until the blade won't swing out any more, then flick it open and closed a few times. It will now swing out, so tighten again, and repeat until it will no longer drop. Now, when you pull it out of your pocket, reach for the lock instead of the thumbstud, retract the lock and give it a flick. Opens as fast as an auto (although you don't have to flick the auto, so it still has an advantage if it were legal). You can close it the same way. Practice for a while and you will forget that the blade swings; it's either open or closed, but ceases to exist in between.

After this, you will only use the thumbstud in sheeple-infested areas. I was foolin' around earlier with a 705 in my left pocket and a 730 in my right. I've practiced enough that I can open them both in unison

Thanks for the help. I tightened it similar to the way you did it. But my fingers are sore from grabbing that lock repeatedly, they aren't used to it yet. Right now I just give it a "boost" with my middle finger and then flick the blade out. Am I the only person who uses his middle finger to open his knives? I did this with my Gerber EZ-Out too, most other knives seem harder to open this way though.
