Crystalize

Hi, I'm new to swords I've been looking at Japanese swords for a while and recently jumped on a tanto that caught my eye. I'm unsure whether it is a genuine article but would love any insight to whether it looks real, what style of tanto it could be and any information you guys might be able to glean about it. The saya appears to be brass with wood inside and the rest seems to be brass as well. I think it might be a shinogi based on the shape but I could be wrong Let me know if you need any other info like sizes and etc and I'll see what I can do Again, any information would be greatly appreciated and thanks in advance.
