Use of the Kodachi, Kunai, or Knife with the Bujinkan Kata 水鳥 Mizu Tori

From http://www.rojodojo.com my training video using 水鳥 Mizu Tori to examine this year's Bujinkan themes. I first studied this kata in 2003 in Japan. But Hatsumi Sensei has never stopped expanding on the theme of Juppo Sessho, and it remains a strong part of the theme this year in Japan. I include methods of using the kukan and the expansion and contraction of space. If you do not own the kukan, then your opponent will own you!
