Generic magic wands.
A wand is a thin stick used in some continua, such as the Potterverse, to perform magic. Where wands are generally required to perform magic, not using one may be a charge.
The wand chooses the wizard, and the wood reflects something about the owner's personality.
The term may also refer to other things of similar dimensions, but this really isn't the time or place for that sort of thing, now, is it?
