You should use the special blades for frozen food. To do this, plug in the appliance and start it up by pressing the switch. Important: hold the blades over the frozen food that you are going to cut and move them backwards and forwards to facilitate the operation. These blades are especially designed to improve cutting and, in particular, for cutting food with a crust (bread, meat, etc.).
The SEB Group, as part of its commitment to Quality, has included "Health and Environment" Eco information on its non-stick Tefal/T-fal products. This commitment guarantees the absence of PFOA, lead and cadmium in Tefal/T-fal coatings and the guarantees that our non-stick products are harmless for the environment and the consumer. This Eco information is based on the regular analysis conducted by independent laboratories in many countries (INERIS in France, ASAHI GLASS FLUOROPOLYMERS in UK, FABES Labs in Germany, MB Labs in Canada, SGS in China) (link to the lab sites).This commitment can be found on the website of the Tefal/T-fal brand, as well as the packaging of cookware with non-stick Tefal/T-fal coating.
