Just getting back to the format of posting ... '
This is a photo of my family of the units....
On the left is the newer one from the early 00's, the middle is my deluxe sos from the 90's, and on the right is the original one from the 80's I think.
The dating is from what I can find on the SAK WIKI on the knife in each set. I hope I got it right.
Thanks for looking.
