Armor out of bonded spren?

[-ACE- he/him]

This may have already been asked, I have no idea, but could you technically make armor out of your radiant shardblade? Sigzil made Aux into a bunch of weird shapes, and as long as everything was connected, and since the material that they turn into is incredibly light, wouldn't it make good armor for any radiant who has sworn the third ideal but not the fourth?

I think that the issue is mostly with movement. Shardmetal is very rigid and as far as we've seen is very difficult to manifest as anything other than one piece. So even though you might be able to manifest the spren as something armor-shaped it would probably be just one single, inflexible piece, which would make moving very difficult. It could work well as a shield, like Kaladin used in WoR, or armor that works better as a single piece (like a breastplate).
