Is my katana real or fake?

Hello there, I'm curious about the authenticity of my katana. Could you please help me determine whether it's a genuine piece or a replica? I've heard that there are many factors to consider when identifying a real katana, such as its construction, materials, and craftsmanship. I'd appreciate it if you could provide me with some insights on how to distinguish between a real and a fake katana, and perhaps even give me a quick assessment of my own sword. Thank you in advance for your expertise and assistance.
