In the anime series Attack on Titan, the remnants of mankind live behind massive walls that are designed to keep titans (giant, zombie-like creatures) at bay. Human soldiers are tasked with killing these monsters, but because these giants range from 3-60 meters tall and regenerate health, they’re rather tough to defeat. Their only weakness is the back of their neck, and soldiers use swords with blades that can detach (because the blades have a tendency to get trapped in titan flesh) to attack that area.
Sounds pretty cool, right? Well, one YouTuber was so fixated on these swords that he built a real life version of the detachable AoT weapon—and it looks like it works!
Watch the sword in action after the break…
