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.
Some survival knives have a hollow handle feature. The movie "Rambo" popularized this style of survival knives. Survival Knives like these are sometimes called "Rambo" knives. One of the selling points to these survival knives is that gear can be stored in the handle. A drawback to many hollow handle survival knives is the handle is attached to and not actually part of the blade. This creates a weaker point that may fail when you need your survival knife the most. There are some hollow handle survival knives that are fashioned out of a single piece of steel. The handle on these survival knives is part of the blade so you do not have the weak point. There is another consideration with hollow handle survival knives. If you lose your survival knife you also lose all the gear stored in the handle.
Knives are already part of your daily life. They can be used for different purposes. It is really best to understand the different types of knives to know what type would be more useful for you.
