Weapon

Hibari's weapon of choice is and has always been a set of tonfas. Essentially, it is a stick with a handle. Knowing Hibari's character, the contributing factors in his weapon choice is probably practicality and strength combined. As he is easily annoyed and somewhat simple-minded, something easy to carry around would be a good choice. In addition to that, he likely chose the weapon for it's strength and ease of use. It is reliable, simple, and brutal - just like Hibari.
