I used to use lots of things. A club, machete, spear, and other weapons that we used in my tribe. During my travels with the Avatar, I wanted to be able to do more. Offer more. All of them had powers that I didn't. So I convinced a swordmaster to teach me. He taught me how to not just use a blade, but how to make it as well. It's why I'm here now. In the smithy.

[So. In the end, it's actually something really important to him.]
