none of the very few supporters of the "they are fake" position have much experience worth noting, to draw from, about daggers.

Well Craig:
I guess you can add me to this list along with Christopher even though I've been collecting as long as you Roll Eyes and even though my issue isn't with the daggers perse it with bogus hallmarked fittings. This sticky little issue just won't go away even though you and the rest of the proponents of this dagger have basically ignored it.
As I stated much earlier I don't really have an opinion of these daggers one way or the other and would have ignored this thread completely if such a glaring error (Hallmarking) wasn't present. And while my tenure with daggers as well as yours has been relatively short I do have 50 years experience dealing with Hallmarked silver.
IMO: Until a satisfactoy explanation is developed as to why a manufacturer in Germany would have ignored Guild requirements and legal requirements these daggers will be in doubt.
