Whilst there may be times and places where it is perfectly legally acceptable to swing a sword around and other such weapons, at many times in history weapons have either been limited to the nobility only (as in the Japan of the Tokugawa Shoguns) or outright banned for almost everybody (as in most Western countries today.) Even in more weapon-friendly fantasy worlds, there may be times and places where weapons are banned for most people (such as at the court of a noble, or in certain taverns whose owners really don't want sword fights in their establishment.) With this is mind, here are 30+ items that can be used as weapons.

A race of beings actually IS invunerable while in adolecence. They age, but cannot be killed. A miniority of the race (1 in 20) does not become invunerable, but rather becomes immortal at some point in thier adolecence, and ceases aging while being vunerable to death in all the normal ways. Another minority (also 1 in 20) Permanatly becomes invunerable after adolecence, but ages twice as fast as the race normally does. There is no known way to test for which of the three traits an individual manifests and the three traits cannot mix, as they are tied to the same gene, as it were.
