Buttonhook → The word is formed from "button" (from Old French *bouton*, meaning a small knob or button) and "hook" (from Old English *hōc*, meaning a curved or bent tool). A buttonhook is a tool used to fasten buttons, combining the concept of a small knob with a hooking mechanism.
Think of a small 'knob' ('button') that you can 'hook' with a tool — that's what a buttonhook is used for.
