Mishnayos Keilim Perek 12 Mishnah 1

טבעת אדם – as for example the ring of a finger. But the ring that they established to gird his loins and to and to tie it between his shoulders is ritually pure, and that is a ring of vessels. And the reason is because Scripture did not include anything other than ornaments of a man, but not the ornaments of an animal and vessels.

קורת החצים (beam of arrows) – there are those who interpret the dung heap that the arrows are placed upon. And there are those who interpret the target of the arrow.

ושל אסירין (and that of prisoners) – that they make like a kind of notch in the beam to bring into it the foot of a man [and they place a long piece of wood on top of it] and one is not able to go out/escape. And in the language of Scripture, they call it a סד/stocks (Job 13:27 – though the verse is slightly misquoted by Bartenura who writes: וישם בסד רגלי – while the Biblical text writes): "ותשם בסד רגלי"/”that You put my feet in the stocks [and watch all my ways].” But the beams of arrows and of prisoners that are mentioned here are of metal and not of wood.

קולר (prisoner’s chain/collar around the neck) – that they place on the neck of prisons. [And it closes]. The Aramaic translation of "ויתנהו בסוגר" (Ezekiel 19:9)/”With hooks he was put in a cage, [They carried him off to the king of Babylon and confined him in a fortress],” with the prisoner’s chain/collar around the neck, and because the prisoner’s collar was made that he would carry with him in every place that he goes, it is considered a usable vessel more than the beam of prisoners which does not move with it from its place. Therefore, the prisoner’s collar/chain is ritually impure.

שיש בה בית נעילה – they make for the chain a lock-piece [and place them on the foot of the horses, and close them with a key, and it is considered a vessel.

לכפיתה (for binding, color-band for animals) – chains that they bind with them the money and the cubs/young animals of small dogs. And they are made for the adornment/beauty and they are an ornament of animals and do not ritually defile.

סיטונות (wholesale provision dealers – of wheat) – large merchants who sell in big measure. And they have a chain that they affix at one end of the measure, a Seah or a dry measure of three Kabs/Tarkab, and its second end they place in a ring that is I the door or in the beam and close it with a key in order that the measure not be stolen.

ושל בעלי בתים טהורים – for it is merely made for adornment/beauty and it is an ornament for the vessel.

מפתח אחד – from one link. People don’t make use of a chain in one link, and it is not a vessel.

או שקשר חלזון בראשה – like the image of snail which is a fish in the see that from its blood they dye the Tekhelet [for the ritual fringes of the Tallit]– he ties it by its head which is made of iron, and it is like a vessel.
