This book is well named. It is far more than a catalog of knots and how to tie them. It is a systematic look at rope skills for climbers, presented from the ground up and back again. It features useful knots for each stage of a climb, describing specific scenarios where selected knots come into play in a variety of tree care and tree climbing situations. Knot savvy comes in handy for life in general, not just for climbing.
Beautifully illustrated, 184 pages.
