It was a bit cleaner when I got it, but it has rusted. It's a model, I believe. I don't think it has a blade pattern, but it might be interesting in its own way. It's made of iron and sticks to a magnet. If sharpened, it might be able to cut paper. The carving is quite cool. It could also be used as a connector when attaching a kozuka (small knife) to a scabbard. Legal item. Will be shipped via Nekopos. #RemnantBlade #AntiqueTools #JapaneseSword #Knife #SwordFittings
