This plugin is as simple as it gets. It adds the fun role playing mechanic of sheathing your swords, and making them appear visibly on your back. All swords are supported, and appear in a sheath(lever) on your back.
Simply type /sheath with a sword in your hand to sheath it, and /sheath with an empty hand to retrieve your sword. You can also shift+right click a block with an empty hand to pull out your sword, or click the lever on your head in the inventory screen. NOTE: Clicking the lever on your head in creative mode will give you a lever, not your sword, this is a Minecraft problem.
sheath.use - gives the player access to the /sheath command
It's really very simple, just drop it into your plugins folder, reload, and enjoy your new role play mechanic!
