When the mail was not riveted, a thrust from most sharp weapons could penetrate it. However, when mail was riveted, only a strong well-placed thrust from certain spears, or thin or dedicated mail-piercing swords like the estoc, could penetrate, and a pollaxe or halberd blow could break through the armour. Strong projectile weapons such as stronger self bows, recurve bows, and crossbows could also penetrate riveted mail. [43] [44] Some evidence indicates that during armoured combat, the intention was to actually get around the armour rather than through it—according to a study of skeletons found in Visby, Sweden, a majority of the skeletons showed wounds on less well protected legs. [45] Although mail was a formidable protection, due to technological advances as time progressed, mail worn under plate armour (and stand-alone mail as well) could be penetrated by the conventional weaponry of another knight.

Its invention is credited to Fukushima Dembei Kunitaka, pupil, of Hojo Awa no Kami Ujifusa, but it is also said to be derived directly from foreign models. It is heavy because the links are tinned (biakuro-nagashi) and these are also sharp-edged because they are punched out of iron plate [37]

Don’t start by making your own jump rings. Seriously. If I had had to make all three hundred jump rings required for my first chain maille project, I would never have gotten to the fun part of actually linking them together. There are so many places where you can buy pre-made jump rings that are perfectly good, it makes sense for a chain maille beginner to buy their jump rings.

Find video tutorials to introduce you to a variety of styles of chain maille weaves. If you've never tried chain maille before, be sure to watch our **How to Open and Close Jump Rings** video, as this is the fundamental skill you'll need for making chain maille.

Chainmail was less expensive than plate armor and this is why it was used commonly by foot soldiers. Mail remained in use as a decorative and possibly high-status symbol with military overtones long after its practical usefulness had passed. It was frequently used for the epaulettes of military uniforms. It is still used in this form by some regiments of the British Army.
