Such a bad idea, but how can one resist the allure of the kitchen-based power tools? It's only an exhibition piece, and not something we could buy, but still. If anyone decides they want to build one of these, you should feel proud of your upcoming sense of achievement. However, try to build in the "cast removal technology" that hopefully prevents you from efficiently slicing off limbs and/or digits. So, to recap: Thoroughly impractical, terribly dangerous, and would take up far too much room in the kitchen. Therefore it's a must-have item. I can't imagine why they don't sell them.
