When you start looking for the best kitchen knife set, it’s a good idea to keep informed on what are the different parts of a knife. For something so simple there are several parts to every knife you should know. Let’s dive into the different parts of a knife so you know what is what.

Handle

There are 11 parts of a kitchen knife, split up into two main areas, the blade and the handle. The handle is where you grip the knife and can come in many shapes and looks. There are many common handle materials. There are wood handles, pakkawood handles, plastic and metal knife handles.

 

Butt

The butt of the knife is the end of the handle of a knife. The butt of a knife can have a cap on the end of it, or it can be a rounded edge.

 

Tang

The tang of a knife is where the metal from the blade goes into the handle covering. There are full tangs and partial tangs, and false tangs.

In the image above you can see that this is a full tang knife. Meaning that the metal runs all the way through the knife handle.  Full tang knives are better because they have more strength and are considered better knife construction. Quality kitchen knives will usually have a full tang unless it’s a partial tang for usage purposes.

A partial tang is when the tang only goes part of the way into the blade of the knife and used more with delicate knives that require more accuracy when cutting like a filleting knife. The last type of tang is a false tang and these are usually a hidden tang that is used in low priced knives and don’t offer much support to the blade or the durability of the knife itself. We’ve had these in the past and the blade will often pop out of the handle.

 

Bolster

The bolster of a knife is the thick part of the blade of the knife that provides an easy transition from the blade to the handle. Not all knives will have this. They are usually dull and serve as a stopping point for your handle grip. They are common on knives with a full tang.

 

Rivets

The rivets on a knife handle are used to secure the handle to the blade to prevent them from separating. If a knife handle is molded, as is with several knife makers, there is no need for rivets. Rivets on knife handles are commonly associated with a higher-quality knife.

 

Parts of a Blade of a Knife

The blade of the knife is more important than the knife’s handle, typically when you are looking at knives. The blade is a piece of steel that serves for cutting. It can be stamped or forged depending on the quality and the knife maker. The metal that is used is very important as well as its Rockwell Hardness Scale (RHS). The harder the knife the longer the knife can keep its edge.

 

Heel

The heel of the knife is the widest part of the knife blade. It is typically connected to the bolster and is at the end of the blade closest to the handle. This part of the knife is wider and can be used to cut denser items like sweet potatoes and carrots.

 

Spine

 

The spine is the top of the knife blade. Unless you have a double-edged blade the spine of the blade will be dull and thicker than the cutting edge. This is not a sharp part of the blade.

 

Cutting Edge

The cutting edge of the knife is often referred to as the blade of the knife. But in truth, the whole half of the knife is the blade. There are several parts of the cutting edge including sharpness, degree of edge, and whether it’s a serrated knife or not.

This is the sharpest part of a knife and comes in a variety of different metals depending on the manufacturer and the location of the metal. The cutting edges in the center is the most used part of the knife for cutting.

 

Belly

The belly of a knife is the rounding or curving part of the blade where the cutting edge rounds to the tip of the knife. This can be used to rock the knife for a style of cutting. Some knives will not have a belly like the Japanese nakiri knives and meat cleavers.

 

Tip

knife tip

The tip of a knife is used for more precise cutting with the knife and because it is further away from the handle you are not able to exert as much pressure as you would if you were using the cutting edge or near the heal of the blade. A knife’s tip encompasses the whole end of the knife (point included) and along with the cutting edge are the sharpest part of the blade.

This is contrary to what many think, the tip of the knife is not the very pointed tip, which is called the point of the knife (see next).

 

Point

knife point

The point of the knife is the pointed part at the end of the knife where the spine and the cutting edge meet. All types of knives will have a point where the piece of metal comes to a point.
