To be honest I'm kinda done with the whole steampunk thing, its gotten terribly predictable and not very interesting.
This is an exception however, because it's just such high quality.
Made by Ian Finch-Field it's made out of tanned cowhide leather with brass rivets and a buckle. It's just a really nice bit of work.
