The Anatomy of a Knife

The knife is such a common object in our everyday lives that most of us fail to see what a complex tool it actually is. Most of us think that a knife has only two distinct parts: the handle and the blade. But, in truth, the knife is much more complex, comprising six separate parts.

When you try to visualize a knife, you will most likely think of the blade. The metallic part that extends away from the handle is officially termed the blade. A cutting edge is ground onto one side of the blade and the tasks a knife is suited for are determined essentially by the shape of its blade.

For instance, a knife can be used for skinning, filleting, chopping, and a number of other duties, depending on the shape of the blade. The strength and durability of the knife depends on the kind of steel it is made of. It is best to make blades out of stainless steel because it has a long life and is more hygienic. Stainless steel does not rust or corrode and it is germ resistant.

The point of the knife performs the task of piercing and stabbing things. We use the point to help gut and clean game as it can pierce through the membrane around the skin and help us get to the meat of the quarry.

The tip, according to many knife experts, is the top quarter of the knife blade. This is the part of the knife that is most used as it does the cutting and chopping. Some consider the point to be part of the tip, though they are actually separate parts of the knife.

The cutting edge is the part of the knife that is...well, designed to cut things. It is the part of the blade (facing away from you) that has been sharpened and honed so that it cuts through whatever needs cutting. While there are several types of edges available, the straight and serrated edges are most common. A serrated edge is good for cutting things like bread while the straight edge is better for trimming meat.

The handle is probably the other part of a knife, besides the blade, that people are most familiar with. Handles can be made using a variety of materials including wood, steel, plastic...basically, the sky is the limit.

The butt of the knife is much like the butt of a gun: it is located at the far end of the handle or the exact opposite of the tip. This is where some companies place a compass that can be pulled out to reveal storage space for things like matches and other survival essentials.

These days, there are hand guards that come with some knives, especially survival knives, which essentially protect your hands from accidentally slipping towards the blade. Hand guard or no hand guard, you should be familiar with the basic parts of a knife to reduce your chances of being injured while using one. You should also learn how to maintain and sharpen your knife to make it last as long as possible.
