User blog comment:Skitzo1/Adding Blut to Quincy with durability?/@comment-5398287-20140408171023

See, there's a problem with that logic. While Hierro is a passive effect that's constantly active, Blut Vene has to be consciously activated by a Quincy. Additionally, Hierro-enhanced skin, when struck, simply acts like steel against steel, creating sparks and stuff; Blut Vene, on the other hand, causes the user's veins to be noticeably darkened when their skin is struck, which means we would've seen those veins if those Quincy were using it when they were shrugging off Bankai and such. So unless Kubo comes out and says every Ritter has Blut Vene that's somehow invisible or something, it's assumptive to claim they're all using it.

As for the Blut Arterie...really? We don't even know what it looks like when in use, and so far none of the Sternritter, at least in the second invasion, have been able to even SCRATCH a Bankai being used against them. It goes entirely against our rules here to assume that the Ritter are using Blut Arterie against the Shinigami when we don't even know what it looks like or how powerful it makes them.
