Question

Why is the cutting edge of a knife made sharp ?​

Answer 1

A sharp knife cut objects better because due to its very thin edge, the force of our hand falls over a very small area of the object producing a large pressure and this large pressure cuts the object easily. While a blunt knife has a thicker edge
