Jazz, you shot a hole in one of my dating milestones on the timeline. Any idea when 84s changed over? I figured the reamers were interchangeable between lines. If that's true maybe they just moved all the old parts to the 84mm line. I did think an ebay photo I was looking at had a corkscrew with no groove together with a no eye reamer.
I appreciate your response. I only recently started collecting so I only have a dozen or so knives to look at. Most of what I know about dating, I got from digging through your old posts on the other board.
