[Feature] Traitor Katana 2.0

[robertGN]

instead of spawning a new katana every time which is needless, why not just shove it in the sheath's contents and bring it in and out?

I was originally going to do this, but the code I was going off of for an example (patchboxes) basically does the same thing. If you could point me towards a better example, I'll go do that.
