Kno-Knonsense Knots by Kenneth Van Gorder is a great little book for the Knot world.

I just read through Kenneth Van Gorder's Kno-Knownsense Knots, and as a lifelong sailor I found the methodology that Ken used to be extremely simple and concise, I have been using knots and teaching marlinespike seamanship for over 50 years and I wish that I'd had his book for all of those years. he has included more than 250 clear photos show methods for tying the 60 essential knots. A third of the knots are tied from the same starting point (a formation that he calls "the pretzel"). The pretzel, which may be formed in one second, makes learning faster and recall easier. Basic knotting under normal conditions is covered first, followed by a chapter on using knot combinations and using knots for outdoor activities. The final chapter covers emergency/survival knotting. It includes one-handed knotting, cold-hand knotting, and knotting in the dark. There are no trick knots involved. Just special methods for knotting-by-touch. Anyone can learn trouble-time knotting. Questions? Ask the author at chemp.earthlink.net. I did,
This book is a necessity for the novice and an asset to the expert, Ken Van Gorder may "knot have been a Boy Scout, but he will keep you tiied up for hours and you will find yourself returning to his text when those "Knotty Situations Arise"
