Covington's Platinum 1000 Series Plated Blades are a significant breakthrough after years of research and development. These ultra-thin blades are made of stainless steel, and designed to conserve gem materials while holding waste to an unprecedented minimum. This makes them an ideal choice for cutting glass and precious materials such as sapphire, jade, ruby, and opal. Because it is a plated blade it cuts at twice the speed of ordinary lapidary blades. The ultra-thin rim cuts with little chipping and leaves a remarkably smooth surface requiring less polishing time. **Get your blades before they're gone!
