Carson's collaborations with CRKT produce some of the knife world's best designs and the M4 is no exception! This is one GREAT EDC knife! The build quality is very nice; from handle through blade (which includes the Auto Lawks feature!), pretty much everything about this knife says "quality". Import? Yep. And a good example of manufacturing quality for any production knife maker. Again, I really, REALLY, wish that CRKT would step up the blade steels a bit. This is yet another design that deserves "better". That said, this is an A+ blade!
