Using your Stelton Trigono Chef's Knife is easy. Just hold it by the triangular handle, which is designed to fit all hand sizes comfortably. Use it for a variety of kitchen tasks like chopping, slicing, and dicing. When using it on acidic foods, don't worry about tarnishing as the knife has good resistance. To keep it in top shape, after each use, wash it with mild soap and warm water, then dry it thoroughly. Avoid putting it in the dishwasher as the harsh detergents and high - pressure water can damage the blade. If the knife starts to lose its sharpness, you can easily sharpen it using a standard knife sharpener. And remember, this item is covered by a 30 - day return policy if you're not satisfied.
