These Cheese and Pate knives are handmade with a high quality stainless steel to provide longevity. The handle has a special heat treatment creating a "burnished finish" which gives it an earthy organic texture.
Due to this particular finish the handle can develop surface rust which is in no way a defect. Simply apply olive oil or any vegetable to restore and protect it.
Hand wash only with soft cloth and warm water if needed. Not intended for the dishwasher.
