It seems the general consensus is that when a manufacturer lists their steel generically as a trade name such as 'Surgical Stainless, or Tru-Sharp', or any of the other names such as these even in carbon steels like CV or Carbon V instead of just listing it for what it is that its because it allows the manufacturer to basically use whatever steel may be a better deal price wise or quantity wise at the time of purchase, which can mean that from one lot to the next the steel used may not be the same steel as the last batch.
In other words you may have two knives both saying Tru-Sharp and one may be 440 steel and another may be a 400 series steel but not 440, but 420J instead while others could be something else. There is no real way to know for sure. I can say that I have Case folders in stainless and carbon steel that cut and hold an edge pretty well. Then on the other hand I can say I have others that are outright crappy performers that don't seem anywhere near as good as the ones I like. Many folks, and especially those attached to the companies that do this will argue these things I've mentioned but the truth is there is more benefit for the company to use a steel anonymously by labeling it this way with a trade name than to do otherwise. From both a marketing standpoint and one to control negative publicity its a win win situation.
