A man on YouTube has decided to build a doubled-sided sword with an embedded electrical stun device.
The electrical weapon would apparently render a target incapacitated, as well as bleeding.
The maker adds on YouTube: "It is insulated in rubber padding and wraped in electrical tape."
Which is helpful. Take a look, above. But don't build one.
Update: an earlier version of this story referred to the device as a 'Taser sword'. In fact it has no connection to the official Taser brand name, and we are happy to correct the error.
