Do you carry a pocket knife? Does anyone anymore? They can be helpful if you need to open a stubborn package or if you need something for the TSA to take from you at the airport. But though they're sometimes useful, they aren't particular fearsome. At least, until Joerg Sprave makes one.
The request line is open on bald t-shirted madman Joerg Sprave's Slingshot Channel, and apparently the one thing you've wanted to see more of is razor-sharp blades slicing through frozen chunks of meat. Thank god.
