Knives are primarily utility hand-held equipment. They are tools that can be used to perform certain functions. As such, there are different kinds of knives that can be used for different purposes. Here is a basic survey of different types of knives known in modern times.
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.
Precision cutting knives or commonly known as thin razor knives have very small blades and very thin handles. In fact, some models are only pencil-sized with half inch thin blades.
