The Mitena di Vongola Primo (lit. Vongola First's Gauntlet) is a gauntlet initially used by the first generation Vongola Boss, Giotto. Through future Vongola technology, the 10th generation Boss, Tsuna, is able to use this weapon when his Vongola Box Weapon Natsu enters Cambio Forma. The gauntlet is decorated with the Roman Numeral "I" on the front to symbolize the connection to the Vongola Primo. When either Giotto or Tsuna focuses all their Flames onto their fist for a single attack, their Gloves change and are capable of delivering a devastating punch to the enemy. After unlocking the Original Vongola Rings, the gauntlet gains several sharp spikes and more power.
