I could've sworn I saw somewhere they were sold in pairs, but searching today I can't find anything to confirm or debunk it. Someone care to help me with this?

Vamblades talk about features when they're used as a pair, but they aren't sold as a pair either.

Thanks.

It might be background fluff that ryyk blades are used in pairs, but mechanically there's no benefit offered for doing so beyond the established rules for two-weapon combat as detailed in the core rulebook or that if you get disarmed of one ryyk blade, you've still got another one in hand to slice up your opponent.
