Hi

,
I’ll preface this by saying I have no personal experience with the 0470. Seeing that I don’t have the cash for one, I’ve been intentionally avoiding it. I mean, why run the risk?
I wrote a fairly detailed opinion on the 0460 with comparison to the 0450 and BM 940-2
which you can read here.. You should check it out...lots of pictures (lots of words too

)
What are you looking for in a kinfe? If it’s just general EDC, I’d vote for the 0450; assuming the ergos work for you the only thing holding it back from perfection is being a bit thick behind the edge. (I prefer the all Ti model, purely for tactile reasons.)
IMO the 0460 is a bit more of a niche knife—but there’s nothing wrong with that! It usually goes into pocket when I’m dressing nice, but it frequently spills over into weekday EDC.
The 0609 was brought up too. For the last 3 weeks it’s displaced every other knife from my rotation, which is highly unusual. I’ll be honest, if the action on my 0609 was equal to that of my 0450/0460, it would be my 100%-perfection/forget-all-others knife. The action is still good, but the lockbar tension on my sample is a bit too strong, so I wouldn’t call it great. IDK if that’s specific to my sample or not—and I’d rather too much tension than not enough.
The actions of my 0450 and 0460 are truly amazing.
I voted 0450.
