[Swordfish]

I`m sorry to contradict you completely. The comparison with a butcher`glove is not reasonable. A butcher`s glove must have small rings to get the feel and mobility of the fingers. A butcher`s glove must must protect only against the cut with a sharp knife and against the penetration of the tip of the knife. Therefore a small ring with a thin wire is necessary and sufficient. But this is completely different than a heavy blow with a sword blade, which has a multiple of energy.
The shirt is of the second half of the 15th century, probably from the last quarter. Every wealthy knight will have worn at this time at least a breast-plate to protect the breast. Why then wear an extremely expensive mail shirt? Only to protect the upper arms?
Such small rings certainly offer protection only against a light blow of a sword. But that is not the point. As already mentioned, the weakest area of such small rings is the rivetting. In the field a mail shirt is worn all day. Any contact with a sharp edge would tear a hole in the shirt. After several weeks, the shirt would be torn. If you compare in reality such a small ring with a ring of a strong fighting shirt, you will comprehend immediately the difference.
I have attached two photos. The first shows strong rings of a short fighting shirt of good quality, with short sleeves, dating c. 1500. The weight of this shirt is 8 kg, it is constructed of c. 22.000 rings with a diam. of c.9.5 mm and a wire diam. of 1.5 mm. The rivet has a diam. of 0.85 mm.
The second photo shows two rings, one from this shirt and another from the Arsenal shirt for comparison. The outside diameter and the wire diameter is ab. the half, how thin must than be the diameter of the rivet? The weight of the small ring is only 1/7 of the strong ring. Such rings could never have sufficient strength for a mail shirt suitable for fighting.
