Katana

For the Gamma Company team, see Team Katana.

The Katana is a special armor attachment in Halo 3 and is unlockable by earning 49 out of 79 achievements or 1000 gamerscore. The katana does not affect the gameplay when equipped.

Characteristics
The katana consists of a normal Hayabusa body with a katana sword affixed to the back with a white attachment, possibly magnetized. The sheath (or saya) of the katana is grey and the handle (or tsuka) is a reddish brown color.

Trivia

 * The hilt of the Katana will poke out through the cockpit of the Hornet or Banshee.
 * The Katana can no longer be unlocked by just earning 1000G in Halo 3. One of the only ways to unlock the Katana after the 1.2 update and 1.3 is to unlock 49 out of the 79 achievements. Because unlocking only 40 of the 79 achievements is worth 1000G, the conclusion is that players must have 49 achievements to unlock the Katana. The Katana, as well as the Security permutations, are fabled "armor" glitches, in which they appear and disappear randomly. With the Security, a 1000 gamerscore locks it in, and for Katana, 1750 guarantees it. Since the release of the Mythic Map Pack, the Katana seems to unlock for those who download early (without the need for 1000 gamerscore OR 49 achievements).
 * McFarlane Toys produces a set titled Hayabusa Katana and Scabbard, containing an Action Figure-sized Katana and its sheath. It was available through the Halo Points promotion.
