Tony, thank you for the kind words.

Rick, you are correct, I was wrong. I was trying to recall from memory, what year it was first advertised in the RMK catalog. With my memory, that is a bad thing to do.
I am in Ireland and my wife is in Canada. So I had her look at my notes about the knife(they are all in Canada)and 1988 was the year it was first advertised in the catalog, so I was told.
