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.

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.
