Thx Fai for pointing important things I didnt remember :p
Considering that Ichigo had combined sword with arm like Aizen did, then Aizen's sword was cracking due to evolution, just like Ichigo abandoned sword to take final getsuga in his grip.
His fullbring power comes from experience obtained in previous battles, that means no more sword for him? :s
I will enjoy their training, since both Ichigo and Ginjou have similar destructive fighting styles :D
