You won't need to use the icon textures for those axes, since they don't have anything unique about them in the icons other than the color effects in the background. You can easily use in-game textures to make weapons that look exactly the same, only with better resolution, and particle emitters for the effects.
Switching the textures isn't too big of a deal, you did a good job with the icon textures. But the handle for Killmaim could stand to have a different texture to it, and to be a bit thinner. It wouldn't make it look anything less like the icon.
Still, good ideas, 3/5. If you improve the killmaim handle I'll consider rating it higher, because I really do like the way both blades, and the handle for Serathil, turned out. The only real problem is with killmaim's handle.
Wow very nice, just a couple things.
1) The handle on the first is way to big for the blade.
2) The handle texture on the first is stretched too bad, try using another in-game texture for that wooded part? I know there's plenty of em'.
All in all these look really cool and are very useful.
