Painting or Palette knives (otherwise known as spatula), are the essential artists tools. It is also suitable for mixing colour or scratching the paint on a painting surface. Long or short, broad or narrow, their flexible, springy traditional or comb shaped steel blades or flexible plastic knives, symmetrical or asymmetrical, with their blunt edges open the way to all texture effects, suited for painting on canvas. The blades have a pointed tip and can be of different lengths and shapes: triangular, rectangular or more diamond like.
Paletter Knives are different from a painting knife which has a straight wide blade and a rounded tip, better suited for mixing paints on the palette. Palette Knives are symmetric, like a kitchen spatula, but often with a slight crank between the handle and the blade. They are primarily used for mixing paint colours, mediums, additives, paste, pigments, and so forth directly on the palette before applying them to a surface.
Painting Knives are blunt with a slightly flexible steel blade and no sharpened cutting edge. They are used in place of a brush for applying paint colours, paste, pigments, and so forth directly onto the canvas or painting surface. Between the handle and the blade there is usually a large crank, to keep the artist's hand off the paint surface. Painting knives come in a multitude of styles, shapes, and sizes.
