Whether on land or water (or hanging from a cliff,) knots can mean the difference between life and death. You should know at least five or six knots, but most only know you basic double knot and slip knot, both of which can part if subjected to enough pressure or done poorly.

The Marlin Hitch Knot is virtually inseparable and the video below shows you how to tie this simple but incredibly durable knot.

Being able to tie a durable knot is critical in many survival situations, bet it securing your survival kit or tying together a shelter or lashing together a raft.

Most know the basics, but few know how to do the Marlin Hitch Knot, one of the easiest and most durable knots in existence.
