Which of the following is NOT a characteristic of a good knot?

A good knot should have specific characteristics to ensure it is effective and reliable for its intended purpose. One important characteristic of a good knot is that it should be easy to tie; this facilitates quick and efficient use in emergency situations.

Another essential aspect is that once it is tied, the knot should remain secure under tension, providing the necessary strength and reliability during use. Additionally, a good knot should have a minimal effect on the overall strength of the rope, ensuring that the rope can still function effectively.

In contrast, a knot that is difficult to untie is not considered a good characteristic. While some knots may remain secure under tension, they should still be manageable to untie when necessary. Therefore, a knot that is challenging to untie may create complications in scenarios requiring rapid release or adjustment, making it less practical for technical rescue operations.
