You now have a foolproof method of navigation and enough light. But you need to sleep and eat. The Gerber Bear Grylls Ultimate pro knife with its full tang 4 ¾” high carbon steel blade is just the piece of survival gear you need to help you harvest materials for an emergency shelter, get a fire started, open cans and if necessary, dress wounds and cut bandages.
I’ll take a person with common sense over one who has a lot of survival knowledge and skills. There is too much emphasis out there on wilderness survival. That will be a rarely needed skill set. More common will be urban survival, and suburban survival. Age and physical condition will have more to do with being able to survive a long-term disaster. As a senior I have difficulty convincing myself and my peers that hard core survival skills will be possible or necessary. We can only prepare for those things we feel we have any chance to survive anyway.
Further interest in the survivalist movement peaked in the early 1980s, with Howard Ruff's book How to Prosper During the Coming Bad Years and the publication in 1980 of Life After Doomsday by Bruce D. Clayton. Clayton's book, coinciding with a renewed arms race between the United States and Soviet Union, marked a shift in emphasis in preparations made by survivalists away from economic collapse, famine, and energy shortages—which were concerns in the 1970s—to nuclear war. In the early 1980s, science fiction writer Jerry Pournelle was an editor and columnist for Survive, a survivalist magazine, and was influential in the survivalist movement. Ragnar Benson's 1982 book Live Off The Land In The City And Country suggested rural survival retreats as both a preparedness measure and conscious lifestyle change.
Here are just a few choice gems from The Prepper Journal's 11 Ways A Condom Can Save Your Life: starting fires (they're great at protecting tinder from moisture), hunting for food (sexiest slingshot ever!), and transporting up to two liters of water (yes, rule 34 applies; no, we won't provide the link). They also make serviceable stand-ins for rubber gloves and can be used to protect the muzzle of your other essential survival tool (killing it right now).
Every year in the US about 150 people die while out and about in national parks, more than 1,000 die in hunting-related incidents and thousands of backcountry enthusiasts get in deep trouble and require a Search and Rescue team to save them; with dozens of those folks dying while awaiting rescue. Most fatalities are the result of poor preparation. Bad weather descends and people get lost. They wander without water or shelter, often injuring themselves in the process. If they survive they often suffer frostbite, hypothermia, dehydration, trench foot or some combination of them all.
