Princeton Catalyst Blades and Mini-Blades are crafted from flexible silicone, resulting in a hybrid tool somewhere between a brush and a palette knife!

Mounted on artist brush handles, Catalyst Blades are designed for use with heavy-body acrylic, oil, and water-mixable oil paints. And, because they're heat-resistant, they excel with encaustics.
 
Artists also use them with plaster, clay, and even frosting! Made of FDA-approved silicone, they're great for food crafting.

Cleanup is a breeze with Catalyst Blades and Mini-Blades. In most cases, they can be cleaned with mild soap and water. The solvent-resistant silicone wipes clean, and dried paint can easily be peeled off their surfaces.  They're also dishwasher safe! Blade heads can be separated from their handles for cleaning and replaced when dry.
