It's the latter. There are some blades in particular that have been waiting to be found. The BP's that tend to drop these are expensive clicks even when the mats are available.
This may be a case where the BP was discovered but not crafted. Auktuma had (not)done that with one of my Toulan blade discoveries.
Gratz to Norrie! Now there is just one more Qataal blade for you to discover - the PayBack.
