One Piece - Knife shaped comb - Portgas D. Ace
This item is a must have for all Ace cosplayers and Ace fans alike. It looks like Ace's knife, but is really just a comb. Nobody will notice the difference as long as you wear it on your belt. On anime conventions you will most likely get through any weapon control with it. If you need to restyle your hair, there's a comb at hand. Banpresto has taken care to reproduce all the details of the item to make it look as authentic as possible, except for the blade. The dagger is altogether approximately 20 cm long.
