No. The blade, called a mixing knife, in a TM5 is engineered in a way that prevents the blades from breaking. The shaft of the mixing knife is equipped with a safety break point outside the bowl, so the pressure required to break the knife will break the shaft before the blade. The blades in a TM5 do not have rivets nor any pieces that could break free. The blades have undergone rigorous testing in many scenarios to be safe.
- What if the mixing knife (blade set) is not working properly in a TM5? It is possible to hear the Thermomix motor moving but the mixing knife is not moving.
- Does the Thermomix contain BPA?
- Are all Thermomix recipes compatible with all models of the Thermomix (e.g. TM5 recipes compatible with the TM31)?
- Is it possible for food to burn and stick on the bottom of a Thermomix mixing bowl?
