I think the most telling points in this thread are putting bad hallmarking on display and no ability to trace these daggers past the mid 70s and the obvious variation in their construction. I stated this thread as just an interested spectator until the bad hallmarks showed up then I started drawing my own conclusions.
The telling point to me at this time is the reluctance of any of the owners of these daggers to post good quality pictures of them in this thread. This speaks reams to the point that "I've got somethng to hide".
