I am pleased to show you my Japanese Navy Officer Dirk/Dagger, this one came from a vet's son in Arkansas, I believe it was never taken apart and has a nice even patina. The grip is genuine ray skin and the scabbard is the shark skin pattern, I took some nice close ups for you guys, the detail is really superb in hand, but the real beauty lies within, the blade is like a mirror! markings under the crossguard show a N inside of a diamond shape and an anchor inside a cherry blossom shape, not sure what the N stands for, maybe Nagano? where it was made possibly, I am assuming this is a early wartime made piece, any help or comments is always appreciated!!
