Best ResponseYou've already chosen the best response.0Seriously? We are splitting hairs here? A knife is a wedge first of all. A screw is an inclined plane, and a pencil sharpener is a wedge and if one of those fancy ones, it has gears. The answer is definitely nutcracker.

Best ResponseYou've already chosen the best response.0What is the main function of a knife? To cut right? The simple machine that cuts is the wedge. Because we are evolutionary creatures, we have figured out that we can cut with more power if we use the knife in a lever fashion. Albeit, a knife is a wedge at its core.
