Answer:
Force And Pressure
Why the tools meant for cutting and piercing always have sharp edges? ... 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.
