Answer 2

It is difficult to cut vegetables with a blunt knife because it has more area compared to a sharp knife,which means that the pressure exerted by blunt knife is less than the pressure exerted by sharp knife.in case of blunt knife even a good effort may go fulfil as the pressure applied by the edge of blunt knife is insufficient to cut the vegetables

(smaller the area higher is pressure

larger the area lesser is pressure)
