A kitchen gadget just isn't a kitchen gadget unless it does something. Spin, slide, or transform, something has to happen. A definition such as this would seemingly imply that by nature of having a moving part, anything could be called a kitchen gadget. (And many manufacturers would happily agree.) However, as nifty a gadget may be--even those with enough moving parts to make a wind-up watch jealous--ultimately, it not only has to do something, but it has to do something useful.
The Farberware Mandoline Slicer Pro Speed Prep with 3 Blades qualifies as a kitchen gadget not only because of its moving parts, but its useful moving parts. Add to that the ability for one-handed operation, and this kitchen gadget touches all the bases. The three interchangeable blades allow for slicing and grating as well as creating julienne strips. When vegetables or cheese are placed in the hopper, a plunger presses down on the payload, creating the necessary force to allow users to squeeze the handle mechanism, creating the desired cut.
To fully round out the pure gadgetry of the device, a blade holder is included to house the blades when not in use. Additionally, the food pusher/plunger detaches, minimizing space so the whole contraption can be stored in a drawer. The entire assembly is dishwasher-safe--something that certainly comes in handy, gadget or not.
