As we've seen in previous chapter, Eren has been shown to be able to:

-Harden his entire Titan body (Titan body remains in crystallized state even after Eren exits Titan form)

-Generate large crystal structures from his Titan body capable of supporting very heavy loads

-Harden his fists, similarly to Annie's Female Titan

These 3 examples show that Eren might have equal as or more control over his hardening powers than Annie. We have yet to see Eren harden his nape, but what I was wondering about was whether or not he could generate weapon like structures from his arms. Perhaps if he faces Reiner and Zeke again (Or their successors, Gabi (or Falco) and Colt) maybe he could generate some sort of blade and use it to his advantage? I personally think this would be pretty cool and effective for Eren, since Titan crystals are probably equally or more durable than diamond. What are your opinions on this?
