Made from high grade carbide steel rods, Siser blades are polished to razor sharp perfection for precise cutting. Compatible with the Siser Blade Housing, 60° Blades click in simply thanks to the housing’s inner magnet. The increased angle of the 60° blade makes slicing through thicker materials like Brick® 600, StripFlock Pro and Craft Felt easier than ever. If you’re cutting specialty materials with increased thicknesses, then you’ll want to keep the 60° Blade locked and loaded.
