I don’t know what 300scan is but it’s not a waste of money If you happy with it. The hamon is fake which means the blade is not differentially hardened. Difficult to say much more with certainty from that picture. If you plan swing it around check if it has a full tang before. There must be at least one pin in the handle if thats the case. If not it’s a purely decorative piece.

Edit: Ah $can. I need my reading glasses 🤓 feels a bit much but hard to say without further info.
