Answer:
The smaller the area, larger the pressure on a surface for the same force. This is why tools meant for cutting and piercing always have sharp edges. By increasing the area we can also reduce the pressure on a surface for the same applied force.

The cutting edges of tools like blades, knives etc., are provided with sharp edges to cut the things easily as the sharp edges has small area on which the force is applied, hence more pressure is applied.09-Jul-2014
