A palette knife is a blunt tool used for mixing or applying paint, with a flexible steel blade. It is primarily used for mixing paint colors, paste, etc., or for marbling, decorative endpapers, etc. The "palette" in the name is a reference to an artist's palette which is used for mixing oil paint and acrylic paints.(source wikipedia)
