Well, any US made knife would be rare in the coming years, but this is just my opinion from the current look of things. Question, if you see a good deal thrown at you, do you normally take a look at your what's inside your wallet first? Catch 22, if you think it would make an immediate investment. It anyone's guess about which stuff in future would turn out having a cult like status, because if it's that rare to begin with than, then its the sellers price from the very start. As in any buys you would make, be sure that you have absolutely everything NIB (papers too), but more importantly that the fit and finish (especially matching grinds) for all cutlery purchases. Nothing like bad workmanship to blow your investment plans. And yes, the CQB 1 would be an interesting matter for speculation be sure you get hold of the ATS 34 version, I suspect the later batches from 154 CM doesn't live up to the expectation in quality of workmanship. That's why you ought to check on the finishing first hand!
