The Lost Ways is a survival book by Claude Davis, originally published in 2017. It offers a guide to the skills, techniques, and strategies that were used by our ancestors for survival. The book is based on old methods of hunting, food preservation, building shelters, and crafting tools, with an emphasis on self-sufficiency in a post-collapse society. Davis presents these techniques as essential for preparing for potential disasters or emergencies, focusing on methods that have been largely forgotten by modern society but were once vital for survival.
