Buck marksman lock test

The gravity issue, I agree with the comment above that the momentum of an (upside down) hit like that will also propel the unsecured lockbar down just enough to pop the blade loose. I've owned one of these and they are great knives (in fact, this makes me think about how I need to chase a grey Ghose down again soon), and this locking system is super unique and ingenious, but not perfect.

Only folding knife I trust to hold up to anything like this are lock backs by reputable makers.
You can make every lock fail, but lock backs are the keep it simple stupid answer to "how tough can we make a pocket knife."
 
Thanks for your answer & introducing me to bump keys. Makes me look sideways at the front door and be thankful for my loaded pit bull and mongrel :). The pit's just for looks though, battle cropped one-eyed rescue, she's useless as a watchdog.

LOL! My dog has never met anyone that he didn't like. If anyone broke in, he would just see them as a new playmate.

Locks just keep honest people honest. When I first got interested in lock picking, I was amazed at how easy most locks were defeated.

I grew up with rascals. One friend showed me in Jr High how he could slip some locks with simple tools (e.g. locked classroom vs. scissors) and crack Master combination locks on lockers in <5 min. He'd do it for the sack lunch inside. Makes you forever careful.
 
Every lock has it's own advantages/disadvantages.

Take the Hawk Lock by G&G Hawk. Sure it gives the safety of keeping your fingers away from the blade path when unlocking. But the v-cutout that secures that shallow bolt fixed in the blade will slip out and unlock when prying. A Gerber Roto-Lock/ CRKT LAWKS/ Extrema Ratio secondary safety however will hold it's own.

Just as Benchmade's Axis Lock can "bounce" from shock and disengage where an old REKAT Rolling Lock will not because the bolt rotates. Two completely different lock designs.
