Force is directly proportional to the area.
Less the area (as in case of sharp knife), less force will be needed.
Explanation:
Pressure is force applied per unit area,
As seen, the pressure is inversely proportional to the area. That means, lesser the area on which the force applied, more will be the pressure.
A blunt knife will have larger contact area than the sharp knife.
That means, more the area, more force will be needed.
Less the area (as in case of sharp knife), less force will be needed.
