I LOVE this thing. I hope you took advantage of the 50% off code he has up right now.
The bolts he sends with it have some thread locker on there, but if you adjust it a few times it will loosen up over time and your keys will start flopping. I added some extra thread locker and it took care of the issue. You will need to do that every time you adjust it.
The thing is great. I have it set so I can just push the release and flip out the knife when I need it and flip it back closed.
I just keep an extra set of keys and use those when I fly...
