Look for ergonomic, comfort-grip shapes and soft-touch materials for better control; non-slip textures to prevent slipping when hands are wet; thumb or finger guards for protection; hanging hooks or loops for storage; and designs that improve leverage for easier cutting.
Serrated or jagged edges help separate sticky slices; sharp stainless-steel cutting wheels slice through thicker crusts; and non-stick or resin-coated blades reduce sticking with tacky toppings.
