I have a Caly 3 in ZDP and the sprint Caly 3.5 in super blue. I really feel that the 3.5, for me, is a better fit - I like that extra blade and handle length - it makes the Caly 3.5 look and feel alittle longer and leaner and I find it sets in the hand more comfortably. I do like the carbon fiber on the Caly 3 better than the "woven" style on the Sage 1 - as noted by prior posters, it looks and feels a bit more upmarket. The smaller size spydercos I own usually do not get assigned pocket time out on the jobsites or in the warehouse, so I find I do not need as grippy a handle. I cannot decide whether ZDP is the blade steel for me, however. I have a Stretch and an Endura along with the Caly 3 in ZDP and I have a heck of a time getting them where I want them as far as sharpness is concerned. I am sure that it has something to do with the technique I am using (sharpmaker used gently). That being said, the edge that I do get lasts a loooong time. All in all, this sounds and looks like a really nice package. I should know, but is this a sprint run? I keep trying to swear off participating in the sprint runs, but find it impossible - the production runs are a bit easier to budget.
