I got mine from Milanoo.com when I cosplayed as Gaara.
I don't know how realistic you wanna get but these come in black, blue, or red (your choice) and have all the villages plus rogue/Akatsuki (symbol w/ slash through it). They're a decent size, meaning not kid size, and have the symbol engraved in the metal as opposed to being painted on. They run somewhere around $3 if I remember correctly.
