Applies some slight variations between the different parts (handle, blade, guard, rope grip). 4 shades between pure black and very dark gray. Do this and it's perfect!

Simple but quite nice. I'd still rather have the galaxy skin in the game but I wouldn't mind this going in as well.

If there's a development team that's using the question "what fantasy am i fulfilling with this?", the answer for a jet black katana is for that ninja perk you're making will appeal to ninjas who delve into their darkest, most aggresive selves to slice up tons of zeds and revel in the beauty of your incredible gore system as a reward for a skillful display of violence. Please make this available whenever that ninja stuff happens, i would pay for this because i'm one of those ninjas

This was a very good idea.
