These knives are bigger and composed of very strong metal alloy. Although they are utility knives also, they are more suitable for cutting very tough objects. These are commonly issued to military personnel as a general purpose tool and additional weaponry.
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.
My opinion, based on experiences I have had as a police officer, while hunting and while camping, is this. The best survival knives are the survival knives you trust with your life AND that you are comfortable using. I use this analogy A .22 pistol is much more effective in the hands of someone that knows how to use it, than a 30-06 rifle is in the hands of someone that doesn't know how to load the bullets or is afraid of it.
