Hello everyone, I hope you can help me out. I could really use a hand in identifying, and determining the age and value of what I think might be an Inoue Shinkai tanto? The scabbard has a small blade with housing attached to the side, the markings can be seen there. The primary blade seems to be in excellent condition with no visible markings or wear. Anyone have some ideas as to what this might be worth, how old it is, and who it was made by?
