杻械（上勅久反下胡戒反玉篇桎梏也穿木為也在手曰杻在足曰械也二字從木丑戒皆聲也）。

Manacles and fetters (杻械: the first character is pronounced *chi* + *jiu* [= *niǔ*]; the second character is pronounced *hu* + *jie* [= *xiè*]; the *Yupian* says they are stocks and fetters; made of perforated wood, those on the hands are called *niu* and those on the feet are called *xie*; both characters take the wood radical, with *chou* [丑] and *jie* [戒] as their phonetics).
