Being able to tie a variety of knots may not be something that comes to mind when you are preparing to survive in the wilderness (or in an urban environment after an economic collapse) but knowing a few advanced knots can save your life. Knots are useful for building shelters, constructing traps, securing a fishing line, and climbing steep terrain. If you use the wrong knot for any of these situations, you may have to cut the knot when you can’t untie it, or have it slip out and come undone. Here are five advanced knots that amateurs can master – and they each have unique applications in survival situations.
