The Universe of Horrors mod adds a mob called Steve Jason Voorhees, which has 400 HP and 4000 XP for defeating him. The mod also adds a weapon called the Legendary Katana, which has 17 damage and 1700 Durablity. And as for the Legendary Katanna, there is no crafting for this item. Maybe Crafting will be added in version 1.1. I don't know. Maybe it will probably be like that. The Legendary Katanna cannot be repaired in an anvil. Maybe it will be fixed in version 1.1. As for the Legendary Katanna, it can very rarely drop after defeating the Steve Jason Voorhees mob because Steve Jason Voorhees holds the Legendary Katanna in his hand. The mod adds other things.

Yes, in version 1.1 of the Universe of Horror mod, I will add the Legendary Katana crafting option, but after defeating Steve Jason Voorhees, he will drop a mask. You can burn it in a furnace to get green metal. In crafting mode, you can make a Legendary Katana weapon from 1 coal and 2 green metal. I will add a new biome that will be suitable for Steve Jason Voorhees. From version 1.1, you won't meet him in the desert. These things and others will be available from version 1.1 of the Universe of Horrors mod.
so in version 1.1 you have to defeat 2 Steve Jason Voorhees to get the legendary katana, 2 Green Metal and Coal, then you need 2 masks (this will be soon from version 1.1) (mask = green metal but you can do it in the furnace from version 1.1) (it is not known when version 1.1 will be)
