Sorry for the noob question but what is RC??
RC, or HRC, is the Rockwell Hardness on the C scale.

These so-called "supersteels" tend to have a HRC in the 60s range. They'll chip because they're hard and hence brittle. Softer steels tend to "roll" over in use.

It is always a trade-off. Harder steels have superior edge retention but are harder to sharpen and even more so when they chip. Softer steels will "roll" over at the edge, making them easier to sharpen but they will have inferior edge retention.
