A ring for a person is susceptible to impurity. A ring for cattle or for vessels and all other rings are not susceptible to impurity. A beam for arrows is susceptible to impurity, but one for prisoners is pure. A prisoner's collar is susceptible to impurity. A chain that has a lock-piece is susceptible to impurity. But that used for tying up cattle is pure. The chain used by wholesalers is susceptible to impurity. That used by householders is pure. Rabbi Yose said: When is this so? When it comes from one door, but when it comes from two doors or if it had a snail[-shaped] piece at its end, it is susceptible to impurity.

If one purchases the scales of wool-dealers, they are subject to impurity, because of the hooks. Of householders, if they have hooks, they are impure. Carriers' hooks are pure. Of merchants, impure. Rabbi Yehudah says, [hooks] of merchants, what is before him is impure, and what is behind him is pure. The hooks of a footstool are impure. Of poles on a bedstead, pure. Of a strongbox, impure. Of a reed-basket, pure. Of a table, impure. Of a wooden lamp, pure. This is the rule: All [hooks] that are attached to something subject to impurity are also subject to impurity. All [hooks] that are attached to something not subject to impurity are also not subject to impurity. All [hooks] that are [detached so that] each one is by itself, are pure.

The metal cover of a householder's box: Rabban Gamliel declares it impure, and the Sages declare it pure. [Covers of boxes] belonging to doctors are impure. The door to a cabinet: belonging to householders, pure. Belonging to doctors, impure. Potholders are impure. Bars of a grate are pure. The iron-shod press beam of an olive press is impure. Hooks that are in the wall are pure.

A blood letter's lancet is impure. The style of a sundial is pure. Rabbi Zadok declares it impure. The pin of a weaver is impure. The chest of grist-makers: Rabbi Zadok declares it impure and the Sages declare it pure. If its wagon is made of metal, it is impure.

A pin that was prepared to be used [as a key] to open and shut is impure. One that is made for guarding is pure. A pin that was prepared to open a jug: Rabbi Akiva declares it impure and the Sages declare it pure, unless they are attached. The pin of a money changer is pure; Rabbi Zadok declares it impure. Three things Rabbi Zadok declares impure that the Sages declare pure: The pin of a money changer, the chest of grist-makers, and the style of a sundial; Rabbi Zadok declares them impure and the Sages declare them pure.

Four things Rabban Gamliel declares impure that the Sages declare pure: The metal cover of a householder's box, the hooked handle of a scraper, unfinished metal utensils, and a plank that has split in two. The Sages agree with Rabban Gamliel on a plank split in two, one [part] large and one small, that the large is impure and the small is pure.

An invalid dinar that was prepared to be hung around a child's neck is impure. So too, an invalid sela that was prepared to be used as a weight is impure. How much can be invalid and be permissible to use? Up until [a] two dinar [coin]. Less than that, it should be cut up.

The pen-knife, the writing pen, the plumb-line, the plummet, the tool for crowding olives into a vat, the ruler, and the base of the scale are impure. All unfinished wooden instruments are impure except those made of [wood of] the boxwood tree. Rabbi Yehudah says, even one made of an olive shoot is pure until it is trimmed.
