Our knives are custom hand made and represent a unique art form. Our original designs and choice of materials gives you a distinctively different type of knife compared to a machine factory finished knife. Knives come with a sheath and may vary from the sheath shown in the picture due to production lots. Variations in colors, Damascus patterns, and finishes are a natural part of artisan hand made knives and add to their uniqueness and beauty. If specified, some knives are made of D2 steel or 440c stainless steel. Because these are hand made knives, and not machined, you will frequently see imperfections, blemishes, and differences in finish materials that are part of a handmade product and natural materials. Color variations are normal. Damascus steel patterns can vary. Thousands of buyers continue to purchase DKC Knives. We are based in the United States and stand fully behind our products.
