There are a lot of amazing things about Fallout, including and, maybe especially, the design. The shishkebab stands out because it’s a flaming sword. The weapon comes back in Fallout 4, and it’s so awesome that Caleb Kraft decided to build it. Since Fallout games take place in a post-apocalyptic environment, the weapons are kitbashed together. For example, the shishkebab is built from lawnmower blades, a motorcycle gas tank, etc — whatever was on hand. Kraft has been plotting the build since he saw concept art of the redesigned weapon for Fallout 4. He ended up altering the design slightly, but the result is still beyond awesome. Kraft documented the four-day build with several videos.
