I originally meant per single blade, $50K for a pair. But I was going from memory so I looked it up, and it looks like $25K for the pair. Still not easily affordable for a family especially when I assume a kid would quickly outgrow them, even a cheaper version.

Yes, real expensive from what I gather on this thread. Too bad they can't come up with some kind of tough plastic that'd be just as springy and durable as the alloy ones, but cheap, and wear like shoe leather.
