I picked up a used one on the forums by combining the shipping with some other knives I was buying. I'm not familiar with this series and was curious about them. The 10Z was much smaller than the other CRKT M16 series I have seen at the local knife counter. The flimsy AutoLAWKS promptly failed and got jammed in the pivot after a few dozen flips (to be clear, I bought this used) so I removed it.
It is still in my knife drawer because after all, could YOU sell a used $10 knife with one of the locking mechanisms removed? I still flip it once in a while, which is fun. I've carried it once or twice. The serrations are a little too cramped and grabby for my tastes and don't seem very useful. Since I've seldom cut more than tape with it I can't speak much to the AUS4, but this knife holds the dubious distinction of having the lowest-end steel in my modest collection.
When I compare it to the $12 shipped I spent for my KABAR Dozier, the KABAR beats it handily in design, utility, aesthetics, steel quality, grind, and construction. If I was specifically looking to try a flipper under $20 right now, I'd try out a Kershaw OD-2.
eneyman, if you really like the M16 concept specifically, this could be a very affordable test drive. It's almost like a cheap clone of the CRKT product line, except that it really is a CRKT.
