The area of contact in a blunt knife is more so it decreases the pressure applied but the area of contact in sharp knife is less so the pressure is more so it is easier to cut. The vegetable cutter edge is very sharp. The butter knife is not as sharp as the cutter. Cutting area is more than that of cutter. As area increases pressure decreases. Hence it is difficult to cut by a butter knife.
