A blunt knife's edge is thicker but not sharp. Hence, it is difficult to cut with a blunt knife.
The sharp edge of the knife has less area than the blunt edge. So we are able to cut easily using less strength with a sharp edge of the knife.
That would be one without a sharp edge..like knife or chisel.
A sharp knife cuts much better than a blunt knife. A sharp knife is less likely skid off and cause an accidental wound.
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.
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 blunt knife has larger surface area than a sharp one. Hence force applied will have its effect on larger area causing it difficult to cut vegetables.(its just like : a nail is hammered into the wall from its pointed side....if tried to hammer on the opposite side the result will be nothing.Aki ...
By erosion of the cutting edge
Blunt lances and swords without a sharp edge.

Many dive knives have blunt (squared-off) tips. This makes them safer. You're not likely to need a sharp-tipped knife underwater. You're more likely to just need the cutting edge. Sharp tipped knives tent to snap off and break when prying at things. The blunted tip is more practical as you never need to stab anything but you often need to pry things underwater. A sharp knife is what you need for cutting line and old netting etc.
