We’ve all been there… We need a food item sliced in half, and we need it done as quickly and aggressively as possible. The Rocket Knife, brought to us by The Backyard Scientist, has answered our slicing prayers.

Although it may not fit on most countertops, our new favorite kitchen gadget is an ordinary kitchen knife mounted to an aluminum base on a graphite-lubricated track. Light up the attached rocket and, at 150 mph, the knife perfectly bisects anything placed in its path. It even makes for a high-scoring round of Fruit Ninja.
