I used to be a prop builder like you, but then I took an arrow to the knee.
But seriously, Skyrim is so hot right now! I was just recently commissioned to build a replica of Mehrune's Razor! This thing is gigantic and awesome. I've been having a lot of fun with the build.
This is the main reference that I've been working from.
From that reference and some other in-game shots, I came up with a full scale vector that I printed.
As per my usual style, this is is being build with layers of foam PVC.
Here is the blade and hilt, mostly done and primed (cause it makes it looks pretty).
