Keilim 14:4

The parts of a wagon that are susceptible to ritual impurity are: the metal yoke, the pin, the wings that hold the straps, the iron bar under the animal’s neck, the support, the girth (i.e., the chain to the yoke), the bowls of the yoke, the clapper of the bell, the hook and the nail used to separate the various parts.

Keilim 14:5

The insusceptible parts of a wagon are: a yoke that is only metal-plated, wings that are strictly decorative, tubes that whistle, the lead on the side of the animal’s neck, the rim of the wheel, sheet metal and metal plates, and all other nails. Animal shoes of metal are susceptible to impurity but those of bark are insusceptible. A sword becomes susceptible to ritual impurity once it has been polished. and a knife, once it has been sharpened.
