Grizzly bear,
Thank you for the compliments!
I make my own damascus, if your looking for a blade to build a sword around I believe Patrick Hastings sells beautiful blades at a great price. As for polishing I would suggest reading "The Art of Japanese Sword Polishing". Between using layout fluid to highlight scratches and changing the direction of the polish between stones you will be able to remove all previous scratches before moving onto the next stone.
Thank you,
Dan
