And it will progress if laminated over and well oiled?

First things first, ID what these spots are, or are not. Images In general, the problem with pinhole rust, if active, is it will progress unseen beneath the surface. Pinholes are generally taken care of in the regular course of polishing, but a good polisher will not unecessarily remove metal just to remove a deep pinhole. Some polishers seal any remaining pinholes with lacquer. For now you can oil the sword or just spot oil the areas in question, if it's a concern. Don't over oil, it will only pool up and soak into the saya. fd Most informative, thank you. I am still trying to get a picture of the spots. I am convinced the laquering over has occurred. Is this a serious "problem" for the blade?

I actually went over the spots with a relatively small maginifying glass, as well as a toothpick. They are as smooth as the surrounding areas. That being said, do you suggest that I send the sword for polish? It came in nice polish when I purchased it (at least, it is ncie to me). Or can I simply keep the sword well oiled and not worry about it? A $3k polish would be a significant expense at this time. Daniel F edit: Patient Uchiko will not rectify this issue, I assume?

I appreciate the answer. I will see if I can locate a camera that can capture the dots - they are quite small. Daniel F

Hello there. I recently purchased my first Katana, through Aoi-Art. I am extremely pleased with the sword, and enjoy looking at it for hours at a time. I have found three extremely small spots on the sword - approximately 1mm in diameter. They are dark colored, perhaps even brown. One appears in the hamon, the other two elsewhere. I, of course, feared rust. However, when I look at the spots in good lighting, even reflecting different lights off of the spot, the surface of the sword appears to be perfectly flat. I have also passed a toothpick over the spots to feel or any type of surface change, with zero effect. So, my questions: are they very small rust spots? Polished over and thus smooth? Or something that appears in swords of certain quality (or lack thereof)? If I have omitted relevant information, please forgive me. edit: name Daniel F
