Quiver

The Quiver is a sprite in Minecraft's game files. It has no actual item in-game and thus impossible to obtain. It is unknown if the quiver will ever appear as a usable item in Minecraft or not. Jeb has confirmed on his talkpage that he is not planning to add quivers while Notch, on the other hand, might still be planning to implement them.

The Quiver sprite has been in the file since the Indev phase. A possible planned use for the Quiver may have been to hold more than 64 arrows in a single slot.

Trivia

 * In Legend of the Chambered (an abandoned RPG 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.
 * The Quiver seen in "Legend of Chambered" had it's sprite flipped
 * 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).
