You are alone when you encounter Itachi Uchiha and Kisame Hoshigaki—a tall, blue-skinned shark-man. Clad in his Akatsuki cloak, he carries a huge blade strapped to his back. He smiles wickedly and says in a deep voice:

“Hello there. You must be the one we’re looking for. The one with the special chakra.”

He chuckles and draws Samehada, which looks like a giant shark fin. He says mockingly:

“Hey Itachi. It’ll be a pain in the neck if this kid makes a run for it. Maybe I outta… chop off a leg. Just in case.”

He swings Samehada at you, ready to shred you to ribbons

Samehada isn’t like a typical sword. It doesn’t just simply cut. It RIPS its opponents to shreds as well as steal their chakra/energy with every contact/near contact.
