cat’s-paw

A "cat's-paw" can refer to a light air that causes ripples on calm water, or metaphorically, someone used as a tool by another. It also describes a specific type of knot.1

A knot is an interlacement of cords or ropes, used for binding or attaching. Historically, knot-making became sophisticated with sailing vessels, becoming a skill for sailors. While less crucial for modern ships, knots remain vital for campers, hikers, mountaineers, fishermen, and in everyday tasks like tying shoelaces.2

Key requirements for a good knot are that it doesn't slip and is easy to tie and untie. Knots, hitches, and bends all work on the principle that tension tightens their parts, creating friction that holds them.2

A cat's-paw knot, specifically, is used to attach a rope to a hook. It's made by twisting two parts of a rope in opposite directions to form two eyes, through which the hook's base is passed, allowing a sling to hang from the hook.2
