How to swap weapon models?

I tried swapping Tusk’s model in pickable_item.xml into Radzig’s sword by swapping the model name (long_sword_a to long_sword_henry) but it’s not working for me.

I’m new to this and I tried searching for a solution online but I couldn’t find one so I would appreciate any help.

For reference,
Tusk Sword ID: a4861145-5574-4482-8719-2b7e0f46dfb4
Radzig/Father Sword ID: d7a081e8-2b8c-49d0-915d-2d3c8d4c5274

using the cheat mod the ID is : ui_nm_sword_long_new_home
Strangley for me it has no name. and specs:
min str: 0
stab:58
slash:58
Blunt:3
defense: 0
charisma: 1
durability :1
Wt.: 0.1
price: 0

Yeah but I did a lot of digging in the files and if you use that ID with cheat_add_item it gives me Tusk. I don’t know what’s going on but I did some digging and used some mods as references and my guess is that something about pickable_item.xml is off because I’ve tried changing different things but it wasn’t working. I don’t know though I could be doing something wrong.
Also just to be clear, if you check in player_item.xml and CTRL+F for a4861145-5574-4482-8719-2b7e0f46dfb4 you’d find that it’s for ui_in_long_sword_new_homes that’s how I found it.
