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.
The selection of survival knives is a personal choice. Evaluate what type of terrain you will be in (Desert, Jungle, Woods, Rocks), what your most likely needs will be (digging for water, building a fire, making a shelter, cutting bandages, gathering food), your own physical strength (Don't buy a 5lb. Knife if you can't use it) and keep in mind the points discussed above. When you make your selection remember - Cheap is not a bargain when you need to survive. You do not get any ribbons for finishing second in a survival situation!
These knives normally have longer blades also. Handle designs would be very similar with switch or retractable blade knives. Most designer knives will fall into this category.
