I've never worried about it, all my knives are slotted to be users, even if they don't make it into the rotation much. There are a couple though that are getting heavy use that I wish I'd have bought a backup for down the road.
It used to be there was no real money to be made in discontinued blades, but over the last couple years the secondary market prices for limited edition production models has gotten so ridiculous that I'd bet a lot of guys are buying them to flip them, just look at the number of new unused hinderers that hit the for sale boards. I know a couple of guys using that tactic to fund their custom habit and doing quite well at it. Even the fact that people are now paying over MSRP for the first couple runs of general production knives is pretty crazy ala the 0770cf selling on ebay for over MSRP and ridiculous prices for limited edition ZT's and Spydercos.
