Well, I'm kinda hoping it's rare, so it'll join my recent "grail" purchases. But a couple issues -- first, let's say Kershaw did a production run of 500 of these. They sold enough to establish $400 as a legitimate first-sale price. Then they have a big chunk of the remainder for special gifts -- politicians, high-level dealers (with the understanding there'd be NO resale, at least for a set time period), other individuals in the industry they want to curry favor with including the trade press, retiring employees in lieu of a gold watch, perhaps a few sent back to Hitachi for steel testing, internal R&D a few, and so on.
Let's guesstimate this chunk of production at 20%, or 100 of my [imagined] 500 blades. Let's further stipulate, since I'm just spitballing here, that the entire project was funded by retail sales of the first 200 (or 295) knives through the website.
Question now -- if you were the competent manager of Kershaw production lines, would you not want to pursue such an approach? The number in the open market is still severely limited and they're worth at least 175% of the Kershaw ask, right out of the gate. (Check Ebay.) You've got plenty to distribute internally, for all the above-cited reasons. You made the entire production pay for itself. You even have retail customers who paid $400 considering themselves lucky! Finally, you still have an inventory to carefully leak into -- and control pricing in -- the secondary market.
