it cuts better because it is sharper. the force exerted on it is greater than it would be if it was blunt.
The area on the tip of the blade is small meaning the pressure exerted is all at the end of the tip making it easier to use.

yes it is easier to cut with a sharp knife than with the blunt one because the force applied by the sharp edge is on less surface so it cuts easily than blunt one

as pressure(p)=force(F)/area(A)
so,pressure is directly proportional to force applied on it
and inversely proportional to the area.

same with the knife the sharp knife have less area than the blunt knife so the pressure increases in sharp knife
