The blade on survival knives. As a rule of thumb you should avoid survival knives with a double cutting edged blade. This weakens the tip and also increases the risk of getting cut while performing tasks with survival knives. Some of these tasks may include cutting, slicing, prying, chopping or digging. Fixed blade survival knives should have a full length tang. This means the blade on survival knives should be a single piece of steel that runs all the way through the handle. The blade should be good quality steel that is strong and will also keep a sharp edge.
One of the most common features is a section of saw like teeth on one side of the blade. These teeth are often marketed as being a saw that can be used to cut wood. Due to the design of the teeth and the limited length of most survival knives their usefulness as a saw is limited. These teeth on the survival knives were designed so crews could more easily cut through the relatively thin metal skin on a downed aircraft. These teeth can be used to scrap wood or bark to make tinder to help start a fire. Some survival knives do have actual saw type teeth on the blade. You are still limited in what you can cut by the length of the survival knife blade.
Survival Knives do not have to look fancy. A good solid useful design is what you should be looking for when evaluating a survival knife. Any knife can be used as a survival knife if that is the only knife you have.
