Well, basically.. i decided i wanted to look better than Splug. So here i am, rogue with duel thunderfury

It was simply a matter of extracting the model and texture and placing them in my data folder, so wow reads my weapons to have that particular model and texture.

Looks like those swords are too heavy for you to hold. =)

-Splug

we undead are a weak creature =\

In seriousness, my arms are now another 5 inchs longer
why cant i be a big thunder elemental

Which file do you have to edit to change your weapon models? I found mount models

you have to put in a model and texture named whatever the weapon is called. (so you can make your own )
for example,
model = Sword_1h_Horde_C_01.m2
texture = Sword_1h_Horde_C_01Copper.blp
now, the actual model and texture, are the exact ones used for thunderfury so it will replace my weapons with thunderfury.
there are programs to extract files form the .mq files which is what you will need, search through the files to you find the right one you want, extract, rename and dump in your data directory, and voila your weapon is now (weapon of your choice)

dw hand of rag imo
