You deserve the best, we provide services in all aspects. First, by sliding around the pizza wheel and locking the lid, you and your loved ones can prevent sharp blades when not in use. Second, the shield protects the blade in your drawer so that other objects do not damage or passivate the stainless steel. Hand-held design provides leverage and control for easy slicing. The stainless steel wheel makes it easy to cut thin or thick-skin pizzas. The pizza blade is heat resistant, BPA-free, and made of FDA approved materials.
