Princeton Catalyst Mini-Blades are made of the same, high-quality silicone as the original sized blades and are ideal for adding small details to your work. These blades are an innovative substitute for sharp palette knives and fettling tools. These perfectly flexible blades are great for painting or adding small details to ceramics. The FDA-approved, food-safe, dishwasher safe silicone can also be used in food crafting. The silicone is solvent-resistant and easy to wipe clean with mild soap and water. Blades can even be separated from the wood handles while cleaning and replaced when dry.
