Stainless steel isn’t called no-stain steel!
NEVER put your knifes in the dishwasher! It isn’t good for the steel nor the handle. Do not leave your knife in water.
Remember your knife is only as sharp as the person that sharpens it. A good sharpening steel and a 600/1000 grit sharpening stone goes a long way. But any way that works for you is great!
Use it, keep it clean and it’ll serve you for many years to come!
