Toon Link, swapping swords?

[Deviruchi]

 I've been making my own toon link, and created it by editing another model (One without a hat, and the sword is different).I was wondering how I would swap out the sword model with one from another toon link, seeing as how I don't like the way the current one was made.

Thanks in advance. ._.

EDIT: So far I've exported and replaced the polygons for the sword and the vertices/normals... but I really don't know where to even start.
