Mail is perhaps what most people think of a medieval soldier wearing. The word maille comes from Latin, meaning ‘web’ or ‘net’. It shouldn’t really be called ‘chain-mail’, which is a modern term.
Mail is made up of thousands of interlocked iron, steel or copper rings or ‘links’. The usual pattern is four rings linked through a fifth - every link should have four others connected to it, two above and two below (except at the edges).
Mail was extremely good protection against the cutting of sharp bladed weapons. For this reason it is still used today by people, such as fishmongers, who work with sharp knives.
It could also provide some protection against stabbing, puncturing attacks, depending on how well made it was.
