Stainless Steel Sword Handle Frying Pan – Advantages and Disadvantages Stainless steel is a popular choice for cookware due to its durability and resistance to rust. However, one potential downside is that it can leach heavy metals, such as iron, chromium, and nickel, into food, especially when cooking acidic foods for long periods of time. While nickel can help with rust resistance and increase the hardness of the stainless steel, it also has no nutritional benefit and can cause adverse health effects for those who are sensitive to it. For those who are nickel sensitive, alternative cookware options may be a better choice. Keep in mind that stainless steel sword handle frying pans that are very low in nickel or nickel-free may be prone to corrosion.
