Worlds Sharpest Katana - (Razor Sharp!)

I tested a cheap katana against a Japanese mat - it failed. So, I decided to make my own, but not just any katana... I used 11 razor blades, each replaceable, to craft a katana that's not just sharp, but maintainable. See for yourself as I slice through materials effortlessly, including that mat. 🔔 Why Watch? 1.
