While looking for tokubetsu juyo blades, found a recent auction at aoi: https://sword-auction.com/en/product/26297/as25027-刀無銘近景第24回特別重要刀剣/ I think it's not normal to see bids on tokubetsu juyo given the price points. I'm wondering what this TJ Chikakage is good for. I can see it's very healthy for a 700 years old blade, has fine jigane and maybe a textbook example of sanko-boshi. Any ideas?
