To a person with a hammer everything looks like a nail, so it's no surprise that kitchenware company Microplane is finding more uses for the sharp blades they're pros at producing. When tenderizing meat most of us break out the tenderizing mallet, cover the target with Saran Wrap to avoid splatters, and pound away; but Microplane's Easy Prep Meat Tenderizer proposes you can do this more easily and gently. By rocking this vicious ninja-looking tool across the surface of the meat, you cause the sharp stainless steel blades to sever meat on the fiber level.
A plastic handle covers the blades when not in use, then snaps onto the handle when you need to expose the blades. The whole contraption looks a lot cooler than a mallet-style tenderizer, but I wouldn't look forward to having to clean one of these.
