Chain mail for Larp and show fight
Chain mail is probably the type of metal armour that has been in use the longest. Developed far in antiquity around the year 500 BC, they remained in continuous use in some parts of the world until the beginning of the 20th century. Today they are still in use by butchers and shark researchers, for example.
The advantages of the chainmail in battle made it attractive to many people. Knights usually wore an additional chain mail under their plate. But also foot soldiers and mercenaries used chain mail for protection. It hardly or not at all restricts movement, it reliably protects against cuts and also limits stabs and projectiles. Although it was expensive to manufacture, it was very easy to maintain and repair. In addition, a chain mail can be combined well with other armour (e.g. plates/sheds/lamella armour). In Larp, chain mail is often used as armor and fits a lot of character concepts.
Protective effect of a chain mail shirt in the Middle Ages
The most effective protection is provided by a chain mail shirt worn over a padded doublet, as this helps to better distribute the force of an attack. It also protects against chafing and pressure points on the skin.
Historical chain mail shirts were actually always riveted or welded, the individual rings were closed with rivets or hot forged. There were only a few exceptions, which probably served more for decoration.
