I believe that mine was around 1992 or 1993. It was a combo-edge Delica, and I think that at the time they were done with a 60/40 edge. I do still have that knife. It's not in great shape but it's functional. I remember being upset with some side-to-side blade play, so I took to it with a hammer and a punch, and hit that pivot rivet, and really made it pretty tight. I remember lusting after, but never buying, the green micarta Goddard and Goddard Jr.
The first time I ever saw
a Spyderco knife was when my brother was in the Army around 1989 or so. He brought home a Delica (I think, but I'm not sure, that it was fully serrated) and showed it to our family, and I remember thinking, "That is the ugliest knife I've ever seen in my life." Nowadays, I think, "Wow, that thing is a work of art!"
