Not quite a brush, and not quite a palette knife. Catalyst tools are crafted from heat and solvent resistant silicon to allow artists a new form of mark-making.

  • They are available as hand held wedges, or as removable blades mounted on traditional brush handles.
  • Catalyst tools can be used with all forms of paint colour and mediums to create exciting new and experimental effects, mixing the tradition of moving paint with innovation through design.

31st January 2018 Reviewed by Olga FitzGerald Exceptional with oil pastels. My pastel teacher recommended it, you use less pastels because this blends it so well. My friend uses it with charcoal and oils as well

15th April 2016 Reviewed by Briony Watson I have used these blades before and am very pleased with them for oil painting but it is a personal choice as to whether you want to paint in this manner. Only gripe is the wrong information on the website about size.
