Change Item Model based on item name [1.8.9]

[Megabaum]

I started a few days ago with Forge modding. (I've got some Java experience). 

So I decidet to make a little mod, which could change the model of items, based on their name. (example: I rename a diamondsword to legendary sword and then it would change the model).

And I would like that the mod also runs on vanilla servers, so it must be client based. ( --> It can't add new items)

 

I had success when I tried to replace the model completly, but that isn't that what I want.

ModelLoader.setCustomModelResourceLocation(diamondSword.getItem(), 0, new ModelResourceLocation(MODID + ":aspect_dragon_sword", "inventory"));

 

Now I have some questions:

1.How could I switch between different models?

2.Where should I put the code? (I'm a noob) 

 

Thank you guys!

1.8.9 is so freaking old we don't support it any more.

1.8.9 is no longer supported on this forum due to its age.

Please update to a modern version of Minecraft to receive support.
