The only CRKT I currently have is a Viele Wasp and the lock works very well and seems much more robust than the liners of the M-series. I've handled quite a few M-series folders, some virtually brand new (maybe a few weeks old). With a few flicks of the flipper, I was able to get the liner full to the other side of the tang, regardless of whether it was the cheapo zytel version or the nicer aluminum ones. This was only maybe 3-4 flicks by me, and a few by my friend before me. Even one brand new out of the box did that in a dozen or so flips. Considering the M-series are supposed to be flicked open with the flipper, it's bad that the liner wears so quickly to the other side of the tang. I have other liner locks that I flick/flip or are assisted (so it flicks for me) that I've done many more hard opens on and the liners are still not even at center tang. As someone said above, there are so many other choices for the price, so I'd rather look at those. And as others have said, I love their designs (M-series and others), but don't like their execution.
I do, however, like their frame locks like the My Tighe (well, everything, especially the aesthetics, except the 1.4116 steel...eh).
