exrema ratio fulcrum or golem?
A knife can be classified as a Class 1 lever. The classification of levers is based on the relative positions of the effort (force applied), the fulcrum (pivot point), and the load (resistance or object being moved). In a Class 1 lever: Fulcrum (F): The fulcrum is located between the effort and the load. Effort (E): The effort is applied on one side of the fulcrum. Load (L): The load is on the other side of the fulcrum. In the case of a knife: Fulcrum (F): The point where the knife pivots, usually where the handle meets the blade. Effort (E): The force applied by the user to cut or slice through the food. Load (L): The resistance or the material being cut, such as vegetables, meat, or other food items. When you use a knife, you apply force (effort) on the handle, causing the blade to pivot around the fulcrum and exerting force on the material being cut (load). Class 1 levers are characterized by their balanced arrangement, where the effort and load are on opposite sides of the fulcrum.
Knife edge: Knife edge scissors are made with the balance beam or lever arm fulcrum in the form of a hardened steel "knife edge' wedge; used to minimize friction. http://www.marthastewart.com/good-things/knife-edge-pillow
That would be a wedge as the blade is sharpened to an edge. It could also arguably be a lever, the chopping board being a fulcrum.

The fixed point of a lever is called the fulcrum. A lever is a beam connected by a hinge, or pivot, called a fulcrum. A lever is used to amplify the applied force.
The knife is a third class lever. The pressure is applied to the other end of the handle nearest to the blade and the fulcrum is at the end of the handle nearest to the wrist.
The fulcrum. A Lever is a rigid rod to which a force can be applied to overcome a resistance. The point at which a lever pivots is called the fulcrum.
