Well, I used lemon juice to bring out the hamon on my blade, and it worked great, the only issue is that the lemon juice stained some areas of the blade, and I can't get the stains out. I tryed steel wool and Dawn soap, but no amount of rubbing will get them out! How can I remove these stains? Can I use Flitz? Also, How do I put a nice satin or scratchy finish on the blade, so scratches it gets while wood-chopping won't be as noticable? Thanks all!
