A sharp knife cuts fruits and vegetables more effectively as its sharp edge has less area . This decreased area increases the pressure and fruits, vegetables are cut easily.

(we know p=kThrust/area)
the knife edge is sharp and has less area
pressure is inversely proportional to the area of contact so we can cut the vegetables and fruits easily with less force
