Grumbacher's plastic palette knives tackle mixing and application without the weight or cost of metal alternatives. Ten-inch length provides comfortable reach across your palette surface while maintaining control during color blending. Tough plastic construction flexes just enough for effective paint manipulation, stiff enough to move heavy-bodied acrylics and oils, flexible enough to scrape surfaces clean without gouging.

Six essential shapes cover standard studio needs: from broad spatulas for mixing large quantities to pointed tips for detailed application and sgraffito techniques. Plastic won't corrode when exposed to acidic pigments or reactive media, and cleanup requires only soap and water rather than aggressive solvents. The material stays neutral with your paint chemistry, never introducing metallic reactions that could affect color or drying properties.

Individual knives let you replace specific shapes as they wear, while the six-knife set equips a new studio or replaces an entire collection at once. These tools handle daily mixing duties, experimental techniques, and teaching scenarios where durability matters more than the refined flex of forged steel.
