Sharpening the blunt tool help in the cutting the vegetables easily because when the tool is sharpened it's sharp edge becomes thin and when pressure is exerted... on any fruit or on any vegetable it cuts it very easily...

Mona sharpens the knife so that Contact of Surface area decreases and the Resultant pressure will be more and the vegetables will be easily cut down. Thus the pressure is inversely proportional to area of contact and directly proportional to the Force applied.

Answer 2

A sharp knife is characterized by a very narrow edge as compared to a usual iron rod or a blunt knife. We apply force on the knife to cut the vegetables. There is a relation between the force applied, the area of contact, and the impact on the vegetable.
