In 1982, Sylvester Stallone burst into movie theaters as John Rambo, former Green Beret and survival master. Watching the movie "First Blood," young boys everywhere witnessed the ultimate tough guy sew a cut on his arm shut with a needle and thread stored in the handle of his jumbo survival knife. The knife that Rambo put on the map in 1982 is still a hot item today with outdoor enthusiasts, hunters and fisherman.
Most survival knives are the same. They have long blades with serrated edges on one side and a hollow handle. Tucked inside the handle is a small survival kit with matches, fishhooks and line, a compass, and sometimes even Rambo's famous needle and thread. When it comes time to buy your survival knife or any knife, you get what you pay for. A cheap knife will have a dull and breakable blade. Once you have your knife you'll want to custom pack the handle depending on your needs. Waterproof matches and a small flint are good ideas, along with some water purification tablets. The fishhooks and line are good to keep on hand for emergency angling, but the needle and thread are really just the stuff of movies. You'd do better to replace them with some pain medication.
