it is well known that pressure is inversely proportional to surface area
So if the pressure will be maximum as surface area decreases which shows the force exerted will be maximum
Hence
blade of the scissors must be sharp to cut the clothes or papers because the sharp thing's molecules apply a force that pushes the other material's molecules apart. The force applied by the sharp thing's molecules is greater than the force holding the other molecules together, so they separate.
