All of my Spydercos are great knives.
If I had to pick ONE MODEL out of all of the knives that I currently have, it would probably be the Yojimbo 2 in 20CV, OR the Sustain in 20CV.
The following are all of my current Spydercos (and I have at least 15 more that are on my want list):
Military S110V, Bob Lum Darn Dao, Yojimbo 2 (ONE) S30V & (TWO) CF 20CV, Sustain, Native 5 Maxamet, Jumpmaster 2.
