Whether you decide to use it or keep it as a collector, I would encourage you NOT to polish out the marks. It is my experience that knives that have been "cleaned" are not as desirable as "original" knives. If you keep it as a collector, the marks will be part of the history. You can never get it back to its original looks. My 2 cents worth. Great looking knife btw. Do you have a picture of the other side of the knife and the back of the sheath? Are you the original owner?
