I dunno, I've lost confidence in liner/frame locks over the last year. I've had a Spyderco Spin eat it's way across the blade tang, until it touched the other scale, and a sprint run OD-1 which failed with a spine TAP against my leg.

If you slowly applied pressure to the spine, you could see the liner sloooooowwwly slide across the tang until it finally slipped off.
I do have other Kershaws which work perfectly fine. It's just that liner and frame locks have always seemed a bit precarious to me, at least in comparison to other locks.
Probably just a personal preference, but I am surprised that Kershaw doesn't have more of a variety of locks to go with their variety of excellent designs.
