Here are a few gizmos i use in the kitchen on a daily basis.
Top left is the mezzaluna knife. It's kinda like what would happen if the rocker knife and a hatchet got down and then had kids... somehow. Also, it chops herbs! Woo!
Moving along in a clockwise fashion, we have the garlic robot. It's basically a mini-cuisinart which is powered by rolling it back and forth on the little grey wheels. It dices 3-4 cloves at a time. I suppose one could use it for making pesto a tablespoon at a time too.
Finally, we have an herb / leafy green slicer my sister gave me. I forgot what it's called, so I refer to it as "Satan's pizza wheel." It slices basil four times faster than a single blade. Also, it's wicked fun to use.
Just don't confuse it with your pizza cutter. Eating 'za a quarter inch at a time is a major drag.
