Can somebody help me identifying this sword? From what I could gather, it is a type 19 Japanese Imperial Sword. I read that the police variants have a 5 petal cherry blossom on the handle's ears while the military ones have a 10 petal cherry blossom. I looked at photos of both variants I could find online and could not see the difference for the life of me. I inclined to think that "my" sword is the police version but I am not certain for sure. Can you help?
