a tool that only lets you move forward, which is more than most people manage
means A toothed wheel-and-pawl mechanism that permits motion in one direction only, locking against the reverse; by extension, any incremental, hard-to-undo change (and, in recent slang, something tacky or unruly).
from First showing up in English around the 1600s as 'rochet,' borrowed from French 'rochet,' meaning a bobbin or lance-head — the word later reshaped by association with 'wheel.' The French term traces back through Germanic roots related to 'rock' (a distaff or spindle), the spinning rod that held wool. So a piece of weaving equipment slowly clicked its way into mechanics. The modern slang sense ('ratchet' meaning trashy or wild) is a separate, much later development — widely thought to be a regional pronunciation of 'wretched.'
