What is a "ratchet"?
A ratchet is a mechanical tool that allows rotation in one direction while stopping movement in the opposite direction. It typically consists of a toothed wheel and a small catch that work together to turn something with small, precise adjustments. Ratchets are commonly used in tools like wrenches and screwdrivers to tighten or loosen bolts and screws efficiently. Additionally, they can be found in some adjustable paintbrush handles, allowing artists to change the angle or position of the brush head easily, making it more suitable for detailed painting tasks.
