Survival’s “I” stands for improvise. If you find yourself in a survival situation, chances are you won’t have every tool you need. This is where improvising come in. What can you do with what you have? Take for instance a screwdriver. Aside from the obvious, it can be used as a pry bar, weapon, digging tool, etc. As always, use common sense when improvising. For example, a rifle is not a good back scratcher.
