This is the Super Sledge weapon from Fallout 3 and Fallout: New Vegas remade for Fallout 4.
Meshes were produced with Blender.
Textures were produced with Substance Painter 2, Marmoset Toolbag 3 and Photoshop CS6.
Big thanks to Stefan Engdahl and Adam Ridsdale for providing me with the crucial help, support and inspiration I needed throughout this project.
