The idea of creating a sword that also acts as a taser seems sort of unnecessary, but that hasn’t stopped someone from making it.
As you can see in the video embedded above, YouTube user jonathanj9969 crafted a doubled-bladed sword with a taser housed in between the very tip. However, the charge itself carries throughout the length of the blades. The handle is insulated in rubber padding and warped in electrical tape, which is sort of important unless you plan on being incapacitated when you try to use it on someone else.
The uber weapon can also be directly charged through an outlet that’s at the other end of the blade. A convenient addition to a ridiculous invention.
And if you’re curious as to how it works in practice, the taser sword’s creator has also uploaded a demo using one of his poor friends.
