Quiver

The quiver is a sprite located in Minecraft's items.png resource file. It has no actual item in-game and thus is impossible to obtain. Jeb has confirmed that he is not planning to add quivers.

The quiver sprite has been in items.png since the Indev phase.

Trivia

 * In Legend of the Chambered (an abandoned RPG that Notch made), there was a quiver item available to be picked up as loot. Notch reused the sprite from that game and put it in Minecraft, albeit flipped horizontally.
 * When loading a level that is using a certain mod item with that item in your bottom slots, the quiver sprite will quickly appear and disappear. This is due to the fact that Modloader considers the quiver an 'item sprite index' available for being overwritten, and will actually be the first one to be overwritten (as it's the first 'free' position in the file).
 * Quivers let you hold more arrows to shoot with a Bow.
