I deeply appreciate this information. Does anyone know if the screw to rivet change went across the entire line (small and large knives) at the same time? I know that when ever Vic makes a production change it can take a year or so for all the existing stock without the change to turn over. These are such extraordinary knives it would be nice to have a reliable history for the line. There are pieces of this history all over the place, but I imagine that the history is especially concentrated in this community. I've seen Vic's letter noting some of the big changes, but to my knowledge nothing comprehensive exisits.
