What does a Cat's Paw refer to in rope terminology?

A Cat's Paw in rope terminology refers to a quick, light-duty eye for hoisting that can untie itself when the load is removed. This knot is particularly useful in scenarios where a fast and efficient means of connecting a rope to a load is required, and it is designed to secure items without requiring extensive tying or untying processes. The self-untie feature is beneficial when the load must be released quickly, making it ideal for hoisting tasks.

The other options do not accurately describe the Cat's Paw. While heavy-duty knots and square knots serve their specific purposes in binding and securing items for heavy lifting, they lack the unique characteristics of the Cat's Paw, particularly its ability to be easily untied under load. Likewise, advanced knots suitable for fishing are specialized for securing fishing lines and tackle rather than for hoisting, which emphasizes how the Cat's Paw is specifically tailored for lighter, quick-release applications.
