How do I remove discoloration or staining from my knife blade?

If your knife blade shows signs of staining, use a non-abrasive metal polish for cleaning or gently scrub a 1:1 mixture of white vinegar and water with a non-abrasive sponge. Rinse and dry immediately.

How do I restore the initial color of my knife handle?

To restore the initial color of your handle, we recommend applying a small amount of oil or cooking spray to a paper towel and carefully rubbing it onto the handle. Rub for about 30 seconds and be sure to fully coat the knife handle. Use care to hand wash the handle with soap and water to remove excess oil. Towel dry immediately. If you are not satisfied with the results, repeat this process. Always carefully wash away all the oil and dry thoroughly before use.
