Tweezers are small tools you can use for pulling splinters or hairs from your skin or picking up tiny objects.
Tweezers is one of those words—like pliers, pants, and scissors—that are always spoken of as a pair, despite being a single object. A jeweler uses tweezers to pick up small beads and jewels, and a nurse uses tweezers to extract splinters. The verb tweeze came from the noun, which is rooted in etwee, or "small case for carrying things."
