This is the best work ever done, under one single cover, on the subject. For all the people that goes to the wilderness (hunters, fishers, backpackers, outdoorsmen), this book is a muust-have. For the people that want to really know the evolution of technology from the early, say "stone-age", standpoint, it's a fascinating work. Specially good the chapter on primitive weapons, with some of the best instructions on the atlatl (spear-thrower or, more preciselly, dart-thrower), the weapon that men of yore used to hunt big game in the stone-age days. I loved it, and I know you'll love it, too.
