仕込み杖 杖刀
The [b]shikomizue[/b], [b]shikomi-zue[/b] (仕込み杖, [i]"prepared cane"[/i]) or [b]jotou[/b] (杖刀, [i]"staff sword"[/i]) is a Japanese [[sword]] [[stick]] or [[concealed weapon]]. 

It is most famous for its use by the fictional swordmaster [[Zatoichi]]. The sword blade was placed in a cane-like mounting ([i]tsue[/i]) as concealment.

Some shikomi-zue also concealed metsubushi, chains, hooks, and many other things. Shikomi-zue could be carried in public without arousing suspicion, making them perfect tools for [[ninja]].
