Man Builds Functional Plasma Core Knife Inspired By Halo’s Energy Sword

With over 15 years of writing experience, Jonathan has had a passion for all things tech-related since watching Inspector Gadget as a child. He's disassembled countless appliances and managed to put a few back together, and one actually still works. When not writing, he can often be found playing video games or accidentally hurting himself tinkering in the garage.

After becoming obsessed with the Energy Sword featured in the Halo franchise, Youtuber Plasma Channel decided to construct the next best thing: a hunting knife with a 20,000-volt plasma core that can cut, shock, and burn simultaneously. I must have one for my own knife collection. Granted, I don’t have a knife collection, but what better way to start one than with a plasma knife?

Named the FS Blade, the knife has a hilt reminiscent of a lightsaber, weighs 0.75 pounds, and measures 14 inches in total length. It uses 80W of power to generate 20,000-volt plasma in the form of ionized air particles blown between the twin blades via a fan in the hilt. Awesome, now I just need one of those real-life lightsabers to complete my once-thought-fictional laser weaponry arsenal.

Is the knife practical? Probably only at looking cool. Sure, it cuts a green pepper in the video, but it’s not exactly a chef’s knife. It also lights a couple of candles and burns the ends of damaged plant leaves, but that’s about it. Still, to be perfectly clear, that isn’t stopping me from wanting one any less.
