There's something incredibly terrifying about a perfect replica of the retractable wrist blade seen in Assassin's Creed.
Don't get me wrong, this is easily the best homemade attempt at recreating the series' signature weapon I've ever seen. That ring-activated extension mechanism is quite a clever bit of engineering, and the actual movement of the blade seems quite fluid.
My horror, I think, stems from all the possible ways this project could go terribly wrong. It's bound to make any murders you commit instantly more stylish, but what happens when you forget you have it strapped to your arm and go to pet your cat?
The answer is not "we all get cake."
