The water in the hobby continues to be muddled. Micrometers, chemical testing, microscopic examinations, etc. Either it's "real" or it's not. This reminds me of the myth of a few years ago that all "smooth-tailed" Himmler's are fake. It gained some traction, until several knowledgeable collectors finally put an end to it. No doubt, some collectors have gotten out their Himmler's and Rohm's, too, to try to determine if the inscription is engraved. This kind of thing can lead to greatly devaluing some daggers. If this course is pursued, it should be done in an independent laboratory with daggers in hand, not through a handful of photos by amateurs.
