Im curious if the springs broke while the knife was in the open position or more likely while it was being opened or closed? In which case, it didnt actually fail (at least when it counts, that is IN USE)
Seems to me the Axis design gives the most warning of a failure more than any other before your in any danger, you have to break both springs before you'd get a real failure ie, having the blade come down on your knuckles,plus they probably only break while opening or closing. Even if both broke you can hold the lockbar in position easily in a jam. A broken spring or springs isn't necassarily a failure of the lock per se, just a failure to lock into position automatically....BIG DIFFERENCE!!
If i had to rely on a locking folder, I'd gladly rely on the Axis with my life due it's abilty to still function manually even with no springs at all, wear proof design, ease of cleaning the lock out, resistance to failing even with slippery crap on the lockbar and awesome outright strength.
When a liner type lock or lockback finally wears, or gets enough slick stuff on the tang there's no warning at all when it fails, plus it will only fail when you would least want it to fail, that is in use with your knuckles in the way of the blade.
The Axis lock is the benchmark to live up to in lock mechs , all that survival stuff is just icing on the cake anyways, for everyday ease of use, reliability, strength and smoothness, there's no finer design. I wouldn't sweat about those springs for a second for any of you considering an Axis lock equipped Benchmade as your next knife, the springs are just a nicety, not a total neccesity.
all just my .02 of course.
