# Knot Tie-ing: Adjustable loop and knot that gets more secure as its pulled

I do some rock climbing, and the most common knot you see is the double-figure 8:

That's because you can tie it at any point in the rope to create a loop for other climbers to latch into. It also gets tighter as you pull from any direction: the loop or either of the two single ropes coming out.

However, I am often faced with a different problem:

Say you have an infinitely long pole that you need to tie a rope around. You have to make a loop that will grip the pole tighter as the rope is pulled. You have access to one end of the rope, not both. You also need a knot that has this property of getting tighter as the rope is pulled.

Is there any such knot that fits this description?

I think I know the knot you are talking about, but I can't draw or remember the name :(

Its basically a situation where you have the main line (rope going to you) sandwiched inbetween two other pieces of rope, and a knot is formed with these two pieces near the pole.

I'd be easy to video conference and show you a crappy demo, but I don't think I can do that. It might be easier if I just told you to ask the guy with the face for some advice ;)
