I should have been more clear in my post, I don't really know why I wasn't. I'm a big fan of the LOTR and The Hobbit movies (and books), as well as an outdoorsman. Weta, the company who designed the props for the films, sells high impact urethane cast replicas of the knives of Nori the dwarf and did sell the one knife of Fili the dwarf.
I'd purchase them but I really want them made from metal and wood so that I can actually use them. I don't have the skill, know-how, tools, or equipment to make these. I know these will probably cost a lot of money and I'm willing to pay for it. I'd also supply the urethane prop replicas to anyone making them for me to use as a reference, as well as all of the pictures I can get. I'd then have to commission someone who works with leather to make the sheaths, but since replicas of these are not sold, they would have to be based entirely off of photos, screenshots, and the knives themselves. It may be a while before I'm actually ready to commission these, I just wanted to have an idea of some manufacturers to look at to get quotes from. If you recommend yourself (which is great), could you please give me a rough price estimate? Just to be clear - I'm only interested in one of each knife, even though the prop of Nori's knives comes with two.
Many people brought up the issue of copyright. I'll point out that lots of people sell homemade prop replicas from LOTR and The Hobbit on Etsy, and 99% I'm sure that 99% of them don't have permission from anyone. I'm also sure that it'd be okay as long as the make or the knives does not make them for anyone else and doesn't sue them to advertise.
