Molded from hard-wearing, off-white ABS Plastic, these 10" painting knives won't corrode or rust like traditional metal knives. Their smaller symmetrical shape is excellent for creating meticulous texture, short quick strokes, and precise details. Their hard angles and stiffness are ideal for sgraffito and press and lift techniques. They are lightweight with excellent balance for extended use. These solvent-safe, easy-to-clean knives can be used with all mediums.
