Which knot is known as a killer knot because it's often used improperly?

Explanation:
The main idea here is why a knot that seems simple can be dangerous when used in the wrong way. The reef knot, which many people know as the square knot, is known as a “killer knot” because it’s quick and easy to tie but unreliable under real loading conditions. If the two ends being joined don’t carry equal tension, or if the rope strands aren’t the same diameter, the knot can slip or come undone when load is applied. It can also be hard to untie once it’s been loaded, especially if the rope is wet or tightly cinched. Because of this tendency to fail under uneven or dynamic loads, it’s considered dangerous for critical bindings, even though it looks neat. By contrast, the bowline creates a secure fixed loop, and the figure-eight knot acts as a strong stopper that resists slipping, so they don’t carry the same risk of sudden failure due to improper loading. (Note: the reef knot and the square knot refer to the same knot.)
