I would agree that the Achilles heel of the Axis lock is the omega springs, obviously. That said, I probably prefer the simpler spring on the BM over something like what you find on the Spyderdo Manix.
I would say that the most aggravating issue with the Omega springs are, as has been mentioned, the hassle of sending the whole knife back for something someone with a torque set and basic mechanical knowledge could change out within minutes.
The perceived fragility of them is a non-issue if I can procure a few on hand for repair. I look at it something along the line of recoil spring life in a semi automatic pistol. I don't really care if the spring should last 3500 rounds or 10,000 rounds before needing to be changed as long as I can get the spring and have it ahead of time to change it regularly or from a prophylactic view where I pop in fresh springs before going into a situation where failure would be worse than just "bad".
Thst said, I will most likely pick up a set of aftermarkets just to keep on hand. The Axis lock is a pretty durable and adaptable lock in a bad situation. If you found yourself in a survival situation and you snapped a spring, you'd still have one limping along...probably longer than you would survive. Even at that, a simple twig jammed behind the crossbar will lock it up well enough.
I would say that there are few folding knives that can have a lock failure and still remain 50% functional for some time before needing to resort to "chimp tool" level of fixes to press them into further service. Still, it would be nice to have all that redundancy with a more universally "reliable" spring.
I'm very new to the Axis lock. I only have two Benchmades that sport it: An Adamas Auto that is about a month old and a Mini that I bought because I enjoyed the full size so much but wanted a lighter EDC tank.
The Auto is what it is. It opens how it opens. I'm not sure how long the Omegas will last acting as the trigger for the knife, but I'm sure they will hold up just fine. The knife has a safety that can lock the blade open if the Omegas fail. However, I generally thumb open the Mini and quietly drop it shut. I really don't like relying on stop bars to completely hault the momentum. I'm hoping to get several years out of both, but I may put together a little repair kit of some off the shelf springs and a small driver. Then I can fix it if I NEED to, or just send it in and wait for them to do the repair. I'm on the fence about picking up a fixed blade Adamas just so I have a 100% back up for any spring issues
