Very few companies today manufacture a pure Kolinsky Sable brush for oils. Hair for this brush comes from the most Northern areas of Russia and is the finest and most expensive hair used in brush making. When using hair of this quality, Richeson uses only the finest and most skilled brush makers. The brush is mounted in a gold ferrule and has a beautiful, long Walnut handle. When an artist's reputation hangs on a brush stroke, when the blending of a color on a cheek bone can make or break a portrait, then the artist must rely on the very finest of tools.
The shape of the filbert is achieved by gently moving the hair in the finger tips of the brush maker to achieve that perfect oval shape. A knife can never touch the hair, the tips are never cut or trimmed.
This brush is full bodied and comes to a razor edge.
The round is a very difficult brush to make correctly. You can not use a watercolor head on a long handle to get a good oil or acrylic brush. In watercolor, you are pushing very thin applications of colored water. Because there is very little resistance, you need a full bodied brush with great snap but little muscle. With oils and acrylics you will be pushing very thick applications of heavy paste-like paint. Here muscle is required. The Richeson Kolinsky Round is hand crafted by master brush makers using the finest Kolinsky Sable.
