Using your Stelton Trigono Bread Knife is easy. Just hold the triangular handle firmly, and slice through bread or other foods with a smooth motion. When using it on acidic foods, there's no need to worry about tarnishing due to the high - quality steel. To keep it in top condition, hand - wash the knife after each use with warm, soapy water and dry it thoroughly. Avoid putting it in the dishwasher as this can damage the blade. If the knife becomes dull over time, it's easy to sharpen because of the great balance of the steel. Remember, this item is covered by a 30 - day return policy if you're not satisfied.
