Writer, photographer, adventurer, and martial arts trainer (Muay Thai), Reuben has spent 30 years hiking and backpacking through the wildernesses of California, Nevada, and Arizona: often with an air of extreme discipline towards his super Ultralight gear. He has traveled abroad in extreme environments, from the cold climate of Alaska and New Zealand to the desert heat of Egypt. He continues studying primitive techniques in survival and the construction and uses of knives and edged tools from places such as the South Pacific, Australia, New Zealand, South America, and numerous countries in Asia. Reuben has published many articles on knife use, Bushcraft, shelters, and remains a lifetime student of survival.
