This is a replica of Kili's bow from "The Hobbit" movies. This version is not functional and it is made of a piece of ebiara wood (for the "arms") and some pieces of maple wood for the 2 central parts bronze-painted. The carvings are all hand-made with chisels.
The original design is by Weta Workshop. I used the picture from the book "The Hobbit Chronicles" by Weta and the pictures from the movie frames as reference, but I took some artistic freedom in the carvings and proportions.
