How to change the plastic to metallic look

[cathm]

Hi! I would like to make their plastic katana knife (the grey part) into metallic material to make them look real.

Could you please help me and guide me to achieve this?  Thanks!

Oh boy!  I've never had a question like this before!

May I see them up close?

Here you go.  I also attached another photo of the metal katana knife that I am trying to achieve here.

Thanks,

Cathy

I'm so sorry Cathy, this is beyond my skill.  I don't know how to do it.
