In order:
Balisong
Plungelock auto/AXIS (tie)
Compression
Framelock
Lockback
Linerlock
I've separated linerlocks because I've pretty much given up on linerlocks. I agree that materials and craftsmanship counts for quite a lot. But the design is fundamentally less safe than a framelock. You could have a linerlock and a framelock with identical strength and thickness, but on a linerlock, you're not gripping the lock closed like you do a framelock.
That said, I now only own 2 linerlocks, and zero framelocks. Both linerlocks are D/A autos (MT LCC and PT ATAC), and I wouldn't bother owning them if they weren't autos. I'm just really not a fan of frame/linerlocks anymore. I can do it easily enough (I've carried them a lot in the past), but I don't like the way you unlock them, with your finger in the blade path. I'm not much a fan of lockbacks anymore either, but I carry one every day (Spyderco Tasman Salt), sometimes two (Calypso 3). Plus you can drop the blade closed to safely close it one-handed, unlike with a frame/liner.
But basically, I've been spoiled by the AXIS lock. At one time or another, I've cut myself opening or closing every other type of lock. Finger in the path of a frame/linerlock. Dropped a lockback closed onto my index finger. Cut the shit out of myself misjudging the length of the Godfather's blade (and that's with the dull side of the blade/tip). Numerous goofs with balisongs (no surprise there). I've even accidentally fired my UTX-70 into my finger. But I've never cut myself with the AXIS lock (at least, in operating the lock).
Come to think of it, I don't think I've cut myself with the Compression lock either. I do own a Yojimbo, and carry it sometimes, and play with sometimes, usually dropping it closed, but I don't think I've cut myself with it. Not a big fan of the lock though. Safe and strong, but awkward.
