Think laser tag, but with foam swords, and you have a pretty good idea with Sabertron is all about. Sabertron employs an accelerometer to detect when and what the sword has impacted. Wireless communication between blades shares this information, which in turn tells the blade when a player has lost health, measured by LED light strips on the handle. The core of the blade is made of ultra-durable polycarbonate plastic, being near indestructible while weighing less than a pound with the foam blade cover. Currently up for funding on Kickstarter, they’ve (unsurprisingly) already reached their goal, but contributing opens up special deals and pricing as usual.
