Because the cutting edge has a smaller area when the blade is sharp so the pressure it can exert increased
A sharp knife requires less force to cut through the apple because it has a finer edge that can easily slice through the fruit's skin and flesh. On the other hand, a blunt knife requires more force to cut, making the process of slicing an apple more difficult and less precise. This extra force also increases the risk of the knife slipping and causing injury.
area of the edge of the blade is smaller for a sharp knife. so for the same force the pressure under the blade will be greater and smaller force required to give the same pressure.
A sharp knife has a thinner blade that exerts more concentrated cutting force, making it easier to slice through vegetables without applying excessive pressure. A blunt knife, on the other hand, requires more force to cut, increasing the risk of slipping and causing accidents. Additionally, a sharp knife produces cleaner cuts, resulting in less damage to the cell walls of the vegetables and a reduced loss of nutrients and juices.
A sharp nail has a smaller surface area, allowing it to penetrate the wood more easily. The smaller cross-section reduces the amount of wood fibers that need to be displaced, making it easier to drive the nail in.
A blunt pin has a larger surface area compared to a sharp pin, causing the pressure to be distributed over a larger area. This requires more force to penetrate the same material compared to a sharp pin, which concentrates the force over a smaller area.
It's sharp - to help it pass through material without causing much damage. A sharp needle will only leave a tiny hole - while a blunt one might tear the fabric.

Blunt weapons have more force, whereas sharp weapons channel the force into a tiny point. Also, Sharp weapons have a nasty habit of stickeing in the zombie...
It is more dangerous like you could injure yourself
A blunt pin has a larger surface area compared to a sharp pin, causing the pressure to be distributed over a larger area. This requires more force to penetrate the same material compared to a sharp pin, which concentrates the force over a smaller area.
You are crushing the onion not slicing it releasing more of the oils.
"The sharp knife goes where you send it, the dull knife goes where it wants" is a reminder to keep your edges sharp. The dull blade is deflected by a hard material.
A sharp tip would take the least force to pound into the ground with a hammer, as it can penetrate the soil more easily compared to a blunt or flat tip.
as the surface area is less i.e. the lesser the surface area the more is the pressure. an example is that an apple is easier to cut with the knife that has a sharp tip than a blunt knife
