      Aria Hossain In physics force=pressure/area. In order to cut food, you have to exert force. According to the equation, force is directly proportional to pressure. A blunt knife has more area around the cutting edge than a sharp knife. So a blunt knife requires more...  more

      Abdullah Julaybib Firstly, you’ll need more pressure to use a blunt knife.
      P=F/A, for a fixed area, force is directly proportional to pressure. If the
      area of a blunt and a sharp knife is same, then doubling the pressure on blunt
      knife means doubling the force....  more

      Abhay Sunny Pressure= force/area, area of sharp knife is less than area of blunt knife, p is proportional to 1/area, so pressure of sharp knife is more than blunt knife.Don't get confused with the wight and pressuring, pressure is the force on a unit area that is...  more

      Abdullah Masud This is simply an example of pressure in our daily lives. Here, according to Pascal's law (P = f/a, where pressure is the force applied over a certain area), the sharp knife can exert greater pressure than the blunt knife, as the sharper knife has less...  more
