The difference between these two grades is in hardness and ductility, due to the higher carbon content of the 440C. So 440C is harder, but less able to resist an impact or bending load which you'd expect from a harder metal.

There's a slight difference in chromium as well, I think. Overall, 440C will generally be harder than 440A, but both steels are good for knife blades.
