Question

why does a sharp knife cut objects more effectively than a blunt knife by lakhmir Singh​

Answer 1

Answer:

Answer: Lesser the area, larger the pressure for the same force applied. Therefore it is easier to cut with sharp knives than blunt ones, with same force.

Answer 2

Answer:

A sharp knife cuts objects better because due to its very thin edge, the force of our hand falls over a sharp small area of the object producing a large pressure. And this large pressure cuts the object easily. A blunt knife has a thicker edge and does not cut the object easily.
