Erm, I really don't want to start another debate here, Dral, but I really don't get how Mifune broke the chain. If you have a chain pinned to the ground by a sword, it's through one of the links. I'm also presuming that Mifune pinned the chain with a downward stab, but feel free to correct me if I'm wrong. How would Mifune have broken the link with a flick of his wrist? there's no space for the sword to impact against the chain, therefore cut it., you'd just be pushing it along. Not to mention Herriman's pulling you upwards and towards him, which would proabably disrupt that seeing as how his leverage is at the middle point of the blade (also a guess, since it was downward stab that pinned the chain down, correct me if I'm wring here too).

Unless if I'm missing something here...
