What simple machines is a steak knife made of?

A steak knife is actually a combination of several simple machines:

* Wedge: The blade itself is a wedge, which is a simple machine that uses a sloping surface to split or separate objects. The sharp edge of the blade acts as the wedge, splitting the steak fibers.

* Lever: The handle of the steak knife acts as a lever. When you grip the handle and apply force, you're using the handle as a lever to increase the force applied to the blade. This allows you to cut through the meat with greater ease.

* Inclined Plane: The angled blade itself can also be considered an inclined plane. It helps to reduce the amount of force needed to cut through the meat.

While not technically a simple machine, the serrated edge of the knife is a key element in its function. The serrated edge provides additional grip on the meat, making it easier to cut through tough fibers.
