However, by the time he reached East Blue, the sword was no longer Arlong's main weapon of choice, but merely as a final resort against powerful opponents. He placed the blade on the wall within the armory room of Arlong Park, until he pulled it out during his duel against Monkey D. Luffy. Several of its blades were broken by Luffy during their battle inside the Arlong Park.
The sheer size of the sword is quite enough to overwhelm an ordinary opponent. Also, the multiple blades means one or two broken teeth will not render the sword completely useless.
Combined with Arlong's natural-born strength, the blade can cause massive devastation. He has shown to swing Kiribachi in a frenzied manner, and perform consecutive somersaulting slashes within the manner of a buzz saw.
