Question

Why does sharp knife cut better than blunt knife ?

Answer 1

Answer:

A sharp knife has a very thin edge to its blade. A sharp knife cuts objects (like vegetables) 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. On the other hand, a blunt knife has a thicker edge. A blunt knife does not cut an object easily because due to its thicker edge, the force of our hand falls over a larger area of the object and produces lesser pressure. This lesser pressure cuts the object with difficulty.

Answer 2

Step-by-step explanation:

heya

The blade of a knife is like a very thin hand. ... When you try to cut a tomato, a blunt knife crushes a wide band of plant cells underneath it but a sharp knife will cut through a single line of cells, separating the long-chain cellulose molecules in the cell wall. The sharpest knives are those with the thinnest edges.
