I think there's a misconception between your professional use of the term stamped and the way it's used here in this context of kitchen knives. We use the term stamped loosely to refer to a knife where the pattern has be somehow cut from either a sheet of metal or bar stock. That method could be stamped with a press and a pattern, or a pattern could be traced and then cut with an angle grinder, or laser or water jet cut.
Furthermore, stamped is not accurate to describe mono-steel knives (I suppose there are pre-fab clad metal sheets - I think Carter uses them for his SS knives, among others) that are not hand forged because there are some makers that hand forge the blank, and then put it in a press with a pattern, and stamp the final shape.
Our little bubble is filled with many misused words. Stamped is going to generally refer to mono-steel steel knives that are fabricated from sheet or bar stock metal, using a press or a cutting method to create a pre-determined pattern, and then ground or milled to finished geometry. Accuracy be damned!
I find no truth what so ever that a forged knife is better in any way, shape, or form than a stamped and ground knife. Just as much care, expertise and skill goes into creating a knife from bar stock as does from forging – perhaps less steps. Nothing drives me more nuts that someone who is very skilled in a certain craft and a particular way of doing something, but the end result has some quirky features that the maker may be adamant about, but actually are not providing anything beneficial to the final product (Jon can relate tho this).
