Hello, I am trying to create an item with using a java class model. For some reason when I put the item in my hand it shows like this: http://prntscr.com/lsvrjf

assets.arsenalmod.models.item.combat_knife.json: 

{
  "parent": "item/generated",
  "textures": {
    "layer0": "arsenalmod:items/combat_knife"
  }
}

ModelCombatKnife class: https://pastebin.com/gezpT9aa

RenderCombatKnife class: https://pastebin.com/QvtPBp21

 

and I have this in my ClientProxy[postInit]

ModItems.COMBAT_KNIFE.setTileEntityItemStackRenderer(new RenderCombatKnife());

 

Update I removed the json file and this happens now:
