Oh, wait a minute . . . ;-)
PS: This reminds me of a popular blade steel that's used in the manufacture of high-end knives. It's called 154CM. The company that manufactures it (Crucible Industries) produced an improved powdered version of 154-CM and called it CPM-154. The difference between 154CM and CPM-154 is neither trivial nor inexpensive. Want to take a guess at the confusion that naming convention caused? To this day, some knife makers will say they've made a knife out of CPM-154CM when, of course, that blade steel doesn't even exist. And unless a buyer knows enough to ask, they have no idea which alloy is being used in the knife's manufacture.
