Catalyst tools are designed with flexible silicone to allow artists a new way of expression. The Catalyst Tool series includes sets of Wedges, Knives and Mini-Blades. The wedges are ergonomically designed to fit your hand, allowing direct interaction with your work. The blades are mounted on wooden planer handles, making it easy to combine tradition and innovation. Our art supplies are designed for use with heavy-bodied paints, but are also at home with oil, acrylic and water-miscible oils. Heat and solvent resistant materials allow these tools to excel with encaustic, plaster, clay and food processing. The silicone design makes cleaning a breeze. In most cases, you will only need mild soap and water. You can even peel dried paint off the surface. No matter the medium or surface, it's easy to create a masterpiece with Catalyst tools.
