Given the ever more superb spring-assisted flippers and thumb-studders available, do automatics still provide a real functional advantage?

That's a valid point. My Boker Kalashnikov auto will open on up and lock if the blade hits something while opening. But I know the L1 won't so I would give it a little wrist flick if I didn't hear the snap. Problem solved easily.
I'm just twice bitten, thrice shy. Never had an unlocked knife close on my fingers (though I have nightmares about it) but I've been poked and cut by wayward blades. Yes the wrist snap will finish the job but when I'm tied up by evil henchmen and only have a couple inches of wiggle room to get my knife and cut the ropes, every little motion counts.

I sure wouldn't want one of my Wicked Edge sharpened knives closing on my fingers! Ouch!! My knife that my son gave me slipped a couple of inches yesterday and gave me a gash on the side of my index finger knuckle.
 
An automatic knife should open and lock every time you hit the button. Between your knife and other posts about Kershaw Launch issues, I get the impression that they are more finicky than they should be.

It does open if I don't stop it on purpose. My L1 is the best $100 I have ever spent. Nothing 'finicky' about it.
 
Hard to say for sure. On a push button auto or an OTF there's usually a little more resistance to popping open if it's dropped or bumped. I had a Kershaw AO slide off my gun cabinet, hit the floor, and pop open. It ended up bouncing over and nailing my foot with the tip. I've had a few knives hit the floor over the years, manuals can still open, but Kershaws usually pop fully open in a dramatic manner. Not sure why we still have prohibitions on autos when in many cases they are no more dangerous, and often safer, than assisted openers. I have a preference for manual or non assisted flipper over both.
 
The reason I stan for Benchmade Axis Assist knives is that they will always open all the way and lock. If interrupted mid-spring they do not sit slack like cheaper assists (SOG, Kershaw etc). That's what makes a good assist better than a manual and in certain circumstances as capable as a folder.

This is one of the many reasons the Benchmade Vector (both 495 and 496) is my favorite and most carried knife model. It opens every time, even if the blade hits an obstruction. The "bias toward closure" inherent in assisted knives also makes it easier than an auto to close one handed.

Overall I think Benchmade makes the best assist mechanism on the market. Whoever said there's no such thing as a high quality assisted knife has clearly never held a Benchmade Vector.

I have been trying to find a knife that will beat this thing for pocket comfort, blade geometry and overall greatness and I can't. Nothing sits as well in my pocket and gives me as much confidence in performance.

Full disclosure: I added a thumb stud because even though the flipper works fine, decades of muscle memory keep leading my thumb to the blade.

I don't have that muscle memory holding me back. 😁 I definitely prefer flippers.

I'll admit, I don't really see the point of an assist on a thumbstud axis folder, I find pulling the axis back and flicking the knife open to be the best option. However it's very necessary on an axis flipper because of the lack of the same detent found on most other flippers. Until they crack the nut of a manual axis flipper, I don't see the Vector leaving my pocket for a long, long time.

Heck, If SOG can make a decent an axis style flipper, I'm sure Benchmade could knock one out of the park, but that's a topic for another thread.
 
Personally I think auto's should have a lock that keeps the blade in place either closed or open. And seriously, if you think there's any fumbling for the button on a well designed knife you're not doing it right.

The only thing better than a Buck 110 with a thumb stud is a Buck 110 with a happy switch!

I wish the auto 110s weren't so much more expensive than their manual brethren! Still not a huge amount of money, but the autos are nearly triple that of the manuals (last time I looked.) I don't see the added costs that warrant the significantly higher pricing.

That's a reasonable point. On the other hand, the S30V versions are "only" double the price of their manual counterparts. 😁
 
But then the spring may be too strong and I'll start having lock-bounce. I like it fine the way it is.
Lock bounce would mean it's failing to "finish opening and lock up." I'm very skeptical that lock bounce is an issue with the spring for the blade being too strong rather than the spring for the button lock being too weak. My ProTech has no issues locking whether I open it normally or if I stop the blade and release it from any point between fully closed and fully open - in either case, it will reliably lock under its own power. If an auto isn't capable of that, something is wrong.
 
I like some of the assisted knives locking methods better(liner/frame). But I don't like some of the complicated internals. The simpler the better on auto and assisted knives. Really, after having knives with bearings I think that washers are still the way to go.

Oh, I thought that lock-bounce was when the blade snaps open so hard that it kicks back out before the lock can lock the blade. Anyway, I'm not worried about it. In an emergency I would be grabbing my fixed blade DEK1 anyway. When I take it apart to clean it I may see about doing something about the weak spring.

That is exactly what lock-bounce is: the blade bouncing off the stop because it failed to lock open. On a button lock, the cause is more likely to be the spring under the button rather than the spring that runs the action. If the blade is bouncing off the stop instead of locking, the lock spring isn't forcing the button into the tang fast enough. You can compensate either by making the blade move slower (weaker main spring) or the lock move faster (stronger button/lock spring). If you have to lower the strength of the blade spring to the point where deployment doesn't continue when you remove an obstruction, that's the wrong solution. Both springs should be strong enough to reliably do their jobs.

I have a bunch of different springs that I bought before C19 hit us. I'll see if one of them will work better. But you guys are right - it should open on up and lock even if something stops the blade after the button is pushed. I have some extra button springs also.

If you haven't already, you might want to try lubing the sides of the button where it rubs the walls of the cavity the spring sits in. It's possible that excess friction is keeping the lock from popping into place.

I keep all of my weapons and knives lubed. There's nothing wrong with the lock, it locks every time. The mainspring is a little weak, that's all.
