Buy the best knife you can afford.
If you can afford a good framelock buy one. Sebenza, Strider, some of the BM offerings, etc.
Keep it CLEAN. Keep crud, muck and other detrius out of the pivot, lock-mech and other important moving bits.
Make sure you have 100% tang to lock contact on that framelock. None of the early lockup nonsense. 100% contact gives you the best odds your knife will not fold up like a cheap hooker taking a belly punch if you have to stab someone with it.
My Sebenzas all have the lockbar travel 100% across the tang. In a photo it is a solid three-point lock-up between the slabs and the lockbar holding the blade solidly in place.
My striders all have 100% contact on the lockbar against the tang. Again, the geometry of the design is what makes it strong and simple.
I prefer a Sebenza for actual working and cutting tasks, though the Strider SNG has better SD ergos for me personally at this point in my own evolution. These knives can interchange in their use and I'm not picking one over the other as a raw tool. Either will serve well.
HOWEVER, since the discussion is about the tool, if you are carrying it as a weapon, try to NOT swap out some sort of "rotation" without a good reason. Each folding knife has a little different feel and technique to opening it, and since self-defense is a high-stakes and high-adrenaline game, your fumbling fingers need to be clamping on the tool out in utter familariaty.
I prefer a knife which gets out of my pocket easily. As a result, I do not carry knives larger than a Sebenza or SNG if they are folding knives. Some of the larger folders have a LOT of handle to remove from your pocket. It's a personal preference.
I used to really like Enduras, Delicas, etc (backlocks) for carry knives, but after having a failure to lock due to a little sand in the lock-notch on the blade, I stopped trusting them for such matters. YMMV.
I've had enough poor experiences with liner locks to never carry one again. The framelock has my hand clamping the lock in place, the liner does not. It's my knife and my reason.
And I recently sent an Axis lock back to BM since it had crud inextricably stuck in the lock and would not engage 100%. BM suggested it was perhaps not the lock for me. I agree, it's not. It relies on a pair of open channels letting crud and grit into the knife and it's lock.
Keeping any of the above clean minimizes these pitfalls, but I prefer the most reliable mech in my own using experience, which is a framelock. Never had one have a failure to lock in 8 years.
