The deep-cut blade has a 2 mm long blade that will cut through thicker materials than the regular blade. The deep cut blade features a sintered tungsten alloy composed of super-fine powder for extra durability. Recommended for use with the Silhouette Curio. This blade is not recommended by Silhouette to be used with the Cameo, however we know customers do have great results using it with the Cameo. H & H cannot guarantee results and/or harm if used with the Cameo. Use this blade to cut thicker media. Also works well with Siser Brick Heat Transfer.
