Kusabimaru sword 3D model

I am beginner in sculpting and in this CGTrader, so sorry if I made any mistakes.

This contain .ZPR file (ZBrush Projec) so you can do whatever you want to do with it, plus I don't know what format of file you guys need.
I think this is high-poly mesh( I might be wrong), it has no textures but as you can see it has colours and materials (materials are all official)

If you want to help me you can tell me, in comments or in private conversation, what I am doing wrong or I don't know, I am open for any suggestions.
