As was stated above, 410 probably wouldn't be what is used in Cutco knives, it is not suitable for hardening to the point that is needed for decent edgeholding. Many stainless knives are made from 440 series stainless, with the only real difference between 440A, 440B, and 440C being the carbon content. Of these, 440C has the highest carbon content and can be hardened the best, but has lower corrosion resistance. Most cheap knives that say surgical stainless are 440A. If you are interested in the alloy compositions I think there is a FAQ here, and there are a number of websites that have tables of the composition of various cutlery steels. I don't recall any off the top of my head, but if no one else pipes in with them, let me know and I will dig them up. All steel alloys are a mix of various alloying elements, with each element giving particular properties to the steel. What works well for one application might not work very well at all for another.
