Hello, personally would not condemn this dagger/blade too fast. First I have learned from several advanced collectors that there did exist Luft and Army daggers with edched blades without the twigs under the eagle. But I know too few about the special features. What I can see is that the mm is stamped which generally is mostly a good sign. The etch seems to be different from the VOOS etching. The pics do not show the eagle very well but, yes, it seems to be the "Gonzo"-type which is mostly a bod sign. So in this case mho is that to classify the dagger/blade it needs a true expert on KREBS daggers and/or etched blades. Regards,
