Jutte

When training with Jutte, and other short weapons, the uke should keep his or her Jutte tucked into the obi.

 " The reason for this is you should learn how to move with/ around your weapons without injury."

Even with techniques like Jutte: Geki Ichi (so no 1) that involve a kick to the abdomen (suigetsu) the Jutte should be worn.

"A swordsman would have a wakasashi there so you have to kick over it.  That is why the kick is to suigetsu."
