Butter Knife Medium Oak A designer butter knife handcrafted from solid oak. I consider this product to be one of the most used tools in the kitchen! Use it for butter, a good soft cheese, or mustard for the Christmas ham. Find more kitchen tools here: tools. Take good care of your Butter Knife. The butter knives are made of wood and cannot withstand machine washing or soaking. Wash it by hand immediately after use. Wipe it off or place it in a cutlery holder. Sometimes cracks appear in the wood. This is completely normal and is due to variations in the material's moisture content. Hugodesigns Butter Knives are oiled with linseed oil, cold-pressed. We recommend this product as we want our Butter Knives to receive the best possible care. Made By Småland
