These tools are equipped with a loading-resistant technology, ensuring they have an exceptionally long life if properly maintained. Following the coating process, all tools undergo brazing, hardening, and tempering to enhance their strength. However, it's important to note that they cannot be utilized on metal or ceramics, as it may cause damage. Additionally, even though the tools are highly robust, dropping them could result in breakage of the 'teeth'. To keep them in optimal condition, a gentle cleaning with a brass brush is all that's required.
