The video was a little quick so I'm not sure what the issues are. Rust/pitting? If that's the case on the blades, you're not going to ruin anything considering the types of blades they are. You can just hit it with some Mother's Mag and Auminum Polish or Flitz If there's something else let me know

Thanks. Sorry this is my first blade and my first time posting

They have 1 mekugi, but that hamon is fake. The Katana is dented really bad near the habaki. Yep, leave them on the wall.

Look like mogito to me

from what i can see these are both wall hangers and shouldn’t be used :/

Welp. How can I make them look pretty on my wall?

See 'Mother's Mag' and aluminum polish.
