Not sure how much can be ascertained about the blade from photos but here are a few. As well as any information about the blade, I'd like to know if there is anything I can do to clean up the blade, it has some staining from light corrosion, nothing too bad, the edge with some chips which I don't actually mind.I was told it was a no nonsense fighting blade which I find appealing but I'd like to learn to appreciate its characteristics more. I'm a collector of arms and armour generally and would like to know more about early Japanese blades
