Using your Opinel 8 Oak Knife with Black Blade is a breeze. For everyday kitchen tasks like slicing, dicing, and chopping, just grip the oak handle firmly and use the sharp black blade. When you're done, clean it with warm, soapy water and dry it right away to prevent rust. Avoid putting it in the dishwasher as the harsh chemicals can damage the blade's finish. Store it in a dry place, away from moisture. And remember, don't use it for prying or any task it's not designed for to keep the blade in top - shape.
