To give a little perspective here to the people who ask, "Why did Spyderco stop making the Slysz Bowie when it's selling for $450?" first, it wasn't selling for $450 before they discontinued it. Two factors jacked up its selling price: (1) Heavy hitters like Nick Shabazz praising it. (Yup, his words move markets, despite the whole "I'm just a humble jackass; what do I know?" online persona. And by the way, I am not at all saying that his praise was disingenuous or that he had some ulterior motive; he really friggin' likes his Slysz, I'm sure.) (2) Spyderco discontinuing it. Someone astutely pointed out that spikes due to (2) eventually resolve themselves. Right after Michael Jackson died, photos of him were going for lots of money; later (long before the documentary came out), those prices naturally cooled off.
Also, remember that Spyderco routinely does things that are difficult to understand. For instance, when they sell a Shaman in M4 in such quantities and at such a price that the whole stock sells out in 7 minutes (yup, I got mine), you have to ask yourself, "Why not sell it at $250, $275, or even $300? Those knives will sell at a considerably higher price than $200, and the only things Spyderco accomplishes by selling their sprint runs below market value are (a) shortages, and (b) a secondary market where the knives will be sold at a price that more accurately reflects their value, where a middleman (the flippers) take another cut. There's nothing wrong with flipping, in my opinion, but I do wonder why Spyderco or BHQ wouldn't want that money for itself. Spyderco and BHQ are leaving money on the table for no reason. Anyway, my point here is that you don't always understand why Spyderco does what it does.
