Trafalgar Law Wooden Sword
Cosplay wooden katana allowed at all conventions
Trafalgar Law, the captain of the Heart Crew, a pirate crew from North Blue.
Due to the large size of his katana, Trafalgar usually carries this sword on his shoulder (unlike the other sword-wielding characters in the series, who carry it on their hips or back).
Sometimes he delegates one of his teammates (namely Bepo) to carry this sword for him.
