Another Team Fortress 2 - The Sniper Update introduces another new item to be included in the imminent Sniper upgrade patch for Valve' teamplay shooter. Here's word on the Razorback, a tribal shield that's been customized for counter-espionage purposes:

The Razorback is a beautiful hand-carved tribal shield, built using indigenous techniques passed from father to son since before recorded time. Sometimes the old ways really are the best ways. And after using the Razorback in the field, we quickly discovered this was not one of those times.

All the tribal craftsmanship in the world, it turns out, cannot stop a modern butter knife. So we taped a car battery to it. Sure, the added weight of the redesigned Razorback’ll slow you down a little. But any poor sap dumb enough to backstab you while you’re sporting one is getting a surprise to the tune of 10,000 volts. Plus, if they want to stab you again, they’ll have to wait until their knife cools down. Which is lucky for you, since the Razorback collapses into a million finely crafted pieces after a single stab.
