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.

It is easier to hammer a sharp peg than a blunt one because the sharp tip concentrates the force applied during the strike on a smaller surface area, which allows it to penetrate the material more easily. This results in less resistance and requires less energy to drive the peg into the surface. In contrast, a blunt peg has a larger surface area, causing greater friction and resistance, making it more difficult to insert.

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...
Using a blunt chisel is more dangerous than a sharp one because it requires more force to cut through the material, increasing the risk of slipping and causing injury. The lack of control with a dull chisel can lead to unintended movements, potentially resulting in accidents. Additionally, blunt tools may lead to more fatigue over time, making users less cautious and more prone to mistakes. In contrast, a sharp chisel allows for cleaner cuts with greater precision, reducing the likelihood of mishaps.
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.
When cooking, it's best to use a sharp knife. A sharp knife allows for more precise cuts, reduces the risk of injury, and makes food preparation faster and easier. Blunt knives require more force, which can lead to slips and accidents. Overall, investing in good-quality sharp knives enhances efficiency and safety in the kitchen.
