Martial arts are primarily concerned with empty hand fighting since a weapon is no good to you unless you have it with you, it is readily available, you know how to use it, and it is useful in the current situation. For the most part, martial arts weapons are useless for self-defense today, but they are still used as training tools and as a part of keeping the history of martial arts alive. They add variety to training and they help perfect skills used in empty hand fighting.
