Weapons are objects, which are meant to cause harm or death to a living creature. There are many kinds of weapons, which can be divided into many categories. Weapons are mostly made by professionals and then sold to the army, police or a gun shop. Despite of that, it is possible to build, more and less lethal, weapons from ordinary items avaiable for everyone. THAT will not be guided here, as it would be illegal (I think). While it is unusual to see weapons being carried around today, they are an important part of history. Some weapons are illegal to own. There are several reasons for this. One reason may be a lack of some kind a license to have a weapon. Other reason is usually a lack of safety from mass production and usage of the said weapon.
