Distaff

A distaff (/ˈdɪstɑːf/, /ˈdɪstæf/, also called a rock^[1]) is a tool used in spinning. It is designed to hold the unspun fibers, keeping them untangled and thus easing the spinning process. It is most commonly used to hold flax and sometimes wool, but can be used for any type of fibre. Fiber is wrapped around the distaff and tied in place with a piece of ribbon or string. The word comes from Low German dis, meaning a bunch of flax, connected with staff.

As an adjective, the term distaff is used to describe the female side of a family. The corresponding term for the male side of a family is the "spear" side.
