When a bow has only 1 shot, if you shot the last arrow then the bow will look like a new one (if you shot again will disappear), then grab the bow and try to place it with right click, the bow will duplicate (the bows are new)...

Easy way to check so you guy don't have to shot 384 arrows (I did, because at first i thought it was a bug with give and the damage value, happened with a new one too xD) use this command "/give name 261 1 383" will give you a bow with only 1 shot.

I'm making a map and I need to use bows with low durability, this is keeping me to release it :/
