Has some completely different variations. Uchidachi starts hasso, shidachi starts chudan. Shidachi threatens, uchidachi cuts to the wrist, shidachi shifts back to the left, lowering the sword and bringing it up again in a U shape, shifts forward again and strikes men. Uchidachi’s strike should be a bit overcommitted. The heel of the aft foot is up a little during the whole tachi uchi no kurai.
