I attempted a replica of the blade given to Paul Atreides in Dune (2021).
Actually, I made 4 of them so far, 3 from wood scraps and one carved from a block of white, translucent acrylics.
The paintjobs involved about 20 layers of 4 different types of paint in 5 colors. The grips are sculpted with epoxy putty, grips and blades engraved with the markings shown in the movie.
