A blunt knife tends to squash the fruit before cutting. A sharp knife will slice through the fruit without squashing. Less pressure is needed to slice with a sharp knife.
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
A sharp knife would have a higher pressure as it concentrates the force over a smaller area compared to a blunt knife. This allows for easier cutting through objects with less force applied.
A blunt knife's edge is thicker but not sharp. Hence, it is difficult to cut with a blunt knife.
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.
blunt means dull or rounded, for example: "A knife has a sharp end and a blunt end ."
A sharp knife will cut/slash/chop easier.
A sharp knife cuts much better than a blunt knife. A sharp knife is less likely skid off and cause an accidental wound.
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.
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.
"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.
That would be one without a sharp edge..like knife or chisel.
Because your knives are all dull. Sharp knives cut tomatoes quite easily.
