Will a Quality Axis-lock Open When Dropped?

You said it !
Makes one appreciate the old school stuff.
I really go back and forth on back locks . I love the clean handle areas where I grip the knife but I HATE slop in the open position . Just got a Spyderco Manbug with the H2 Saver straight serrated blade and a Spyderco Manbug PD 1 and BOTH developed lock rock / slop in the first few days .One presses down to cut something and the blade goes "CLICK" or "KNOCK". I took them both apart and improved the lock fit up but these are kind of pricy little knives to have to do this to .
Love the hell out of both of them though !

For whatever it's worth to you, I've never had blade slop on my open lock-back Bucks. Even cheaper ($30), newer ones. Also not on a 112 or whatever the small pocket-size version of that is, and that one's been through everything including several tours in the dryer. I don't like Buck's customer service these days, but I won't pretend their blades aren't the ones I grab when I need something reliable.
 
If you can use an inertial / wrist flick to open a knife without using the thumb studs, then the knife likely will open when dropped. The heavier the blade, the more likely it is to happen.
 
I wouldn’t be so concerned if a knife opens when dropped. I’d be more concerned about why I keep dropping em.

Sounds like you may need a lanyard or fob!

I’ve never even considered if a knife will open when dropped in selecting knives to purchase. I don’t plan on dropping em hopefully ever. But if I do, thankfully I’m still able to move my feet!
 
I have dropped my Griptilians a few times. Almost every time the blade has popped open, at least partially. I have also had them come open in large pockets, and the thumb studs sometimes catch on my belt as I pull it out of my watch pocket. So they are not very securely closed, unfortunately. Easy opening makes for a much more fun fidget knife though!
 
If you can easily flick a knife open with your thumb then it doesn't seem surprising at all that falling a few feet onto a hard surface can generate enough energy to do the same. I've experienced this with cross bar locks and other locks but I've never thought it was a problem. I can't imagine it's much of a safety issue either.
 
I’ve been careless with my knives, over the years, and dropped many of them.
Obviously, it depends on how strong the detent of the individual knife is, the angle of the fall and height you drop the knife from,
But I bad virtually every knife-lock “fail” to retain the blade when dropped, eventually.
From framelocks, to backlocks, axis locks and liners. You drop your knife on hard surface the “right” way and it’ll open.
 
The lock is holding it opened on that flat section on the rear of the blade by the pivot.
My Griptilian only has a small curved area on the section where the blade is closed to minimally engage the lock. If it required a significant effort to open, you would have to engage the lock pins when both opening and closing the blade. Instead, you can just roll it opened with your thumb on the stud.
