I heard awhile ago that you can create your own weapons in Skyrim. Is that true?
Yessir. In fact, you can go to a mine with a pick, gather ore, take it back to a forge and then make a weapon with it or armor with it. This also suggests will be seeing a return of glass and ebony mines for other materials. What we'll need for weapon/armor types that are made of less obvious material, like Orcish and Elven, isn't yet clear.
It's also been said that you can kill a deer and use it's hide to make a leather hilt for said weapon and other things, but I think this may be a misunderstanding of what Todd Howard said, because he didn't directly say that, but mentioned collecting leather before getting into iron ore and making a weapon out of that. I thought when he brought up the leather, that's where he was going with it, but he never finished that thought, so it's not certain but many sites seem to think it is. On the flipside, no officials have denied that it'll be that complex. I'm just trying to maintain realistic expectations.
