Palette knives for mixing and applying paint

Palette knives are versatile tools for mixing pigments and creating textured effects on canvas. Available in a range of shapes and flexibilities, they suit both oil and acrylic painters who want to experiment with impasto, scraping and layered textures.

Choosing the right knife

Flexible blades work well for smooth mixing and thin spread, while stiffer knives handle thick impasto and scraping tasks. Consider blade length and shape—rounded tips are gentle for blending, pointed shapes allow precise sculpting, and long blades help manage larger palettes.

Common uses and care

• Mixing paint to achieve consistent colour without wasting brushes.
• Applying thick layers for textured, sculptural effects.
• Scraping back layers to reveal underpainting or create highlights.
• Cleaning palettes quickly by scraping paint into a waste container.
• Using as a spatula for mediums and pastes in studio practice.

Invest in several knives for different tasks rather than forcing one tool to do everything. Wipe blades between colours to keep mixes clean, and wash promptly to prevent buildup. Clearance packs sometimes include sets with varied shapes—useful for exploring techniques without committing to expensive standalone pieces.
