Hello, my name is Wayne and I have this sword I purchased a few years ago as a WW2 relic. I suspect it is traditionally made despite the gunto mounts. I am primarily interested in war relics and know very little about Japanese art swords, my main motivation for buying this one is the fact that I have always admired the sword my grandfather brought back from the Pacific and is now owned by my father. The cutting edge of this one is 27" and I can see a great deal of 'activity' in the blade. The tang is unsigned and there is a large ware in the mune. I believe it to be Mino work, but I am not sure. That's pretty much all I know and I would like your opinions. Thanks!
