How To Tie A Bowline
One of the most useful knots you can know. The Bowline forms a secure loop that will not jam and is easy to tie and untie.
The Bowline is most commonly used for forming a fixed loop, large or small at the end of a line. Tried and tested over centuries, this knot is reliable, strong and stable.
Even after severe tension is applied it is easy to untie. However, because it does untie so easily it should not be trusted in a life or death situation such as mountain climbing.
It is said to retain 60% of the strength of the line in which it is tied.
