Which of these knots is specifically identified as NOT a granny knot?

The square knot, also known as a reef knot, is a specific knot recognized for its ability to join two lengths of rope or line of similar diameter. It is formed by tying two overhand knots in opposite directions, which allows the knot to be securely tied and easily untied when necessary. The square knot is a reliable choice for securing two lines together, especially in situations where the loads are not likely to shift, making it very practical for various applications in lineman work.

In contrast, the granny knot, which is often confused with the square knot, tends to slip or come undone under tension because its construction does not have the same orientation for the two ends. This can lead to dangerous situations when the knot is used in tasks requiring strong security, which is why it is essential to differentiate them. The square knot’s distinct structure ensures it remains secure and does not unintentionally slip, highlighting why it is specifically identified as not being a granny knot. Understanding this distinction is important for anyone working with ropes in lineman duties, where safety and reliability are paramount.
