These Vietri Aladdin steak knives are easy to use. Just hold the handle firmly and slice through your steak with a smooth motion. When using, avoid cutting on hard surfaces like stone or glass to prevent blade damage. For maintenance, you can simply toss them in the dishwasher as they are dishwasher - safe. But if you prefer hand - washing, use warm soapy water and a soft sponge. After washing, dry them thoroughly to keep the shiny chrome finish looking great.
