Apparently wearing a saber lame can protect you from the electrical shock of a taser. Won’t protect you from the barbs, however.
This is a youtube video from August 2011 that just recently resurfaced on Digg. While an interesting video, we don’t suggest trying this at home or running out to purchase saber lames specifically as anti-taser defense gear. (It’s much more fun to suit up and fence saber, as the lame makers intended.)
