i hope everything works out. As Calos points out Aoi Arts has one section to sell blades that are Nihonto and one would expect they are "Art swords" to be apperciated and valued as art or collectible, they also have the "practical or For Use" section and these are marketed to be used as a weapon, not as Nihonto or art so if they are functional that seems the important factor. The price paid for a sword may not be based on its "art or collectibe" features, there are very expensive blades made to be used (much more expensive that antique Nihonto) So one thing to remeber is that if Aoi Arts lists the blade under "for use" section he may have been concerned with how it would function, its apperance may have been of secondary importance......... not sure as i do not use swords and have never bought one for use, just my experiance seeing swords for sale
