That´s a tough quest for someone who was not into Spydercos already in the "older days", but just for some years now..
Don´t know if I can come up with TWO, and don´t know if my choice is a "classic model" in the truest sense of the word, but I´d be very interested in and upgraded (better steel), new release of the VAGABOND
Never had one, butI think this is an very interesting design, and a great choice when wanting to bring a small fixed blade, but not on your belt, but rather in your pack or the like.
The second would be the Stretch 1.
I still think it would have its place together with the Stretch 2 (so NOT replacing the "2" again)
Top three going by pocket-time: Endura 4 in VG 10/Micarta-scales; Stretch 1 in VG 10; Endura 4 in HAP 40
