I'll tell you the one knot that I need to learn ... it's the knot that you use for tightening cargo. Imagine you've got some cargo in the bed of a truck, and you tie down with a rope. There's a special knot you can tie in the end of the rope - you just cinch it down and adjust the rope length - and it tightens automatically. That's a really nice knot - but I haven't seen it in any book. If someone knows a reference ... please post.
