It is 3rd class.
No, a knife is not a 1st class lever. A 1st class lever is a system where the fulcrum is positioned between the effort and the load. In the case of a knife, it typically functions more like a 3rd class lever where the effort is between the fulcrum and the load, such as when cutting through food.
Yep ur welcome.
no because a knife belongs to a kind of simple machine that is wedge
No, a nail cutter is a type of first-class lever because the fulcrum is located between the force (your hand) and the load (the nail being cut). The action of squeezing the handles together applies force to the cutting blades to trim the nails.
