When Not to Use a Square Knot

Square knots are not your best choice when you have two different thicknesses you wish to join. They slip when you tie them with a nylon rope and will also slip if it is not under tension.

Critical Tip:

Square knots can be dangerous if misused and should never be used in critical situations where lives might be at risk. This is simply due to the potential instability of the knot.

Unfortunately, many accidents took place as a result of trying to join two ropes with a square knot.
