An artist’s single most important tool in oil painting is the paintbrush. It is the main piece of equipment used to apply paint to canvas. Artist brushes come in a wide variety of types, sizes and shapes. Knowing all you can about the different types of artist brushes available and how they are used, will allow you to choose the right one for each stage of your canvas painting.
A paintbrush’s anatomy is made up of three basic parts. These are the head, the ferrule and the handle. It isn’t necessary to know this to create a beautiful painting, however, by knowing the different parts you will be familiar with various art terms when you hear them.
- Head — The hairs or bristles of the brush. The hairs are made from either natural or synthetic fibers and is what an artist uses to apply and push paint around on the canvas. The head has three parts too. The very tip of the head is called the toe. The fattest part of the head is called the belly and the point where the head meets the ferrule is called the heel.
- Ferrule — The metal cylinder that attaches the head on to the handle and helps hold the hairs in shape. High quality ferrules won’t rust or come loose.
- Handle — The long stem of the brush that is held when in use. It’s generally made of wood or plastic. The length of the handle can vary. A quality brush will balance on your finger regardless of the size.

Artist’s paintbrushes come in a variety of types. Knowing what those types are is beneficial in knowing which brush to use to achieve the effect you desire in your paintings. There are two main types of hairs in paintbrushes – bristle and sable. There is one other type – synthetic, however that one will be talked about last.
Bristle brushes are made from ox or hog’s hair and are usually light in color and have a lot of bounce. The ends of the bristle hairs don’t come to a point, but has two or three V-shaped splits called “flags.” This makes them capable of holding a good amount of paint which is beneficial since these brushes are mostly used when you are applying paint to the major areas of your canvas. After repeated use, the “flags” will become stained by darker pigments, however, this will not adversely effect the brush in any way. In addition, because the individual hairs of the bristle brush are hard or stiff to the touch, they will leave small grooves in the paint. These grooves will remain in the paint until they are smoothed out with a sable hair brush.
Sable hair brushes are soft painting brushes made with hair that comes from animals such as sable, squirrel, marten or mongoose. They are springy and silky to the touch with each strand converging to a fine point. Sable brushes are great for blending, glazing and making soft, less-defined brushstrokes. When compared to a bristle brush, you will notice their hairs are softer and much more delicate. In addition, sable brushes will not leave tiny grooves in your paint. They are capable of smoothing out the brushstrokes left by other type brushes and will give your painting a smoother, softer look when you don’t want your brushstrokes to show. Artists prefer using them for more delicate applications of paint and finer detailed work. Sable brushes are the most expensive and will require more care than all of your art brushes.
The final type of art paintbrushes are called synthetic brushes. They are not made from animal hairs, but are products from man-made materials of either nylon or polyester filaments. Synthetic brushes range from soft to stiff hairs. They can be tapered, tipped, flagged, abraded or etched to increase their paint carrying ability. They are more affordable than natural brushes made from animal hair, however, they are not quite as good. The hairs of these type brushes tend to stick together when they get wet and synthetic brushes are also prone to wear out faster and are harder to work with. The individual strands often spread out in all directions and fall out and can become a permanent part of your oil painting. However, there are some advantages to synthetic brushes. They are less prone to being damaged by solvents, insects or caustic paints. They are also easier to clean than natural hair brushes because the filaments won’t trap paint like natural hairs will.
