I am starting my first project with a nice dubl duck, but it has nicks at the toe. See photo below. I need to remove about 1 to 1.5 mm before I can set the bevel. I think that would take forever with a 1k. I also have an 800 and a 220 . I'm thinking I need the 220 to remove that much material. That's what my experience with knives tells me - unless razors are so thin that I can do it with a 1k. Any advice would be appreciated.
