Hey, if it holds up, it holds up, and no argument here. I simply distrust folders for strength, even with closed back, as one side is open, inviting flexing.

Any flexing can deform locking surfaces through too much engagement pressure, and then also partially or fully unlock a knife twisted the opposite direction. Batoning far worse as lock not held in engagement by hand pressure.

Open back knives flex even more, period. And liners or frame locks twist right along with rest of frame.

So, I buy the stiffest, strongest built which I can find, with thick scales, larger screws, flared spacers for maximum contact both sides.

And yet, still they flex. Pry with a frame lock and watch the lock bar seat deeper or shallower, and perhaps get stuck, with prying loose with a screwdriver rather than re-flexing the knife to free the lockbar instantly adding years of wear.

Paranoid, perhaps, but I still have all my fingers.
