Most survival knives have a multi-purpose blade. The blade can usually perform multiple tasks like chopping,cutting, spearing and prying. The handle often has a lanyard hole so the survival knife can be tied to a pole to make a spear.
Now, knives are made from metal. Some are really sophisticated which are composed of different alloys to achieve strength, durability, and superior sharpness.
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.
