A sharp knife cuts objects better because due to its very thin
edge, the force of our hand falls over a sharp small area of the
object producing a large pressure And this large pressure cuts the
object easily A blunt knife has a thicker edge and does not cut the
object easily The lesser pressure cuts the object with
difficulty
