CPM-M4 is a steel with high carbon content therefore quite hard and can give very sharp edge. It has some Chromium, but not enough to be classfied as stainless, plus it also contains a lot of vanadium, thus striking a balance between rust resistance and toughness. A lot of high end knives use this steel.
