Modding around another mod's API

[mOXkIe]

So I recently learned some basic modding, and I want to do some recipes using items from other mods. I thought I'd start with Thaumcraft. Lets say I want to make a recipe using a Thaumium Sword, how should I use that in the code?

 

Using a regular vanilla item in a recipe would look something like this(probably wrong but you get my idea)

GameRegistry.addRecipe(new ItemStack(MyNewCoolItemUsingTools), new Object[] { "   ", "xyx", "   ", 'x', Item.stone, 'y', Item.swordIron});

 

Working with the Thaumcraft API, what should I replace Item.swordIron with to use a Thaumium Sword? I hope it's not too much to ask for, if you who are reading this don't have time to look at a API and see how it works it's cool.

 

The closest I got was

ItemApi.getItem(ItemThaumiumSword)

GameRegistry.findItem("whatever-name-is-given-to-the-item-in-the-first-place")
