Question

Why do tools meant for cutting always have sharp edges?​

Answer 1

Answer:

The smaller the area, larger the pressure on a surface for the same force. This is why tools meant for cutting and piercing always have sharp edges. By increasing the area we can also reduce the pressure on a surface for the same applied force.

Answer 2

Answer:

Sharpe tools are best for cutting. This is because force acts perpendicularly per unit area. When the tool will be sharp it means that the surface area reduces thus, in this way more force can be applied on an object and it can be cut easily and quickly. So cutting tools always have sharp edges, not blunt edges.
