Handle
A handle was part of a tool that could be grasped by hand.
In 2022, when an alternate future version of James T. Kirk was driving a stolen Dodge Challenger Hellcat and La'an Noonien-Singh was riding shotgun; when he sped up in order to keep up with the van he was pursuing, he told her to "hold on." She then immediately grasps the grab handle in the car. (SNW: "Tomorrow and Tomorrow and Tomorrow")
The Hill People of the Argus River region on Rigel IV used murinite to make the handles of a type of knives which they produced; one such weapon was involved in a series of murders on Argelius II in 2267. (TOS: "Wolf in the Fold")
