Expand your creative horizons with the powerful Knife Blade + Drive Housing. Made exclusively for Cricut Maker and its Adaptive Tool System™, Knife Blade slices through thicker and denser materials such as balsa wood, leather, matboard, and Cricut Chipboard with ease and precision. Perfect for projects with extra dimension like puzzles, dinosaur skeletons, models, leather goods, dioramas, wood decor, and so much more. For more info on blade calibration, cutting times, materials, and more, visit help.cricut.com/knifeblade. Due to longer cut times requiring Bluetooth™ connection, Knife Blade projects are not compatible with iOS and Android devices. To ensure successful cuts, always turn off Sleep Mode on your computer before starting a cut. If Bluetooth connection is broken (which happens when your computer goes to sleep or if you travel out of range), you run the risk of completely starting over.
