I made a sword small using .json because it took up so much space on my screen, i didnt want to make a smaller sword using textures, so now i am here. if you can help out with the code id REALLY Appriciate it!

 {
    "parent": "item/smaller_util",
    "textures": {
        "layer0": "item/netherite_sword"
    }    
}

i added this to my sword, (copied from another website) it worked and made the sword smaller, but now hand holding is weird and just bad
