Here are my CF Delica, Caly III, and Sage, along with a couple of my favorite watches.
Overall.. the Sage is a great CF knife for the money. I agree with many of the positive statements made about the Sage, so won't repeat them here.
Comparing these three CF Spydies, the only thing I can add, is the relative thickness, between the three knives. From Delica, to Caly III, to Sage, each knife is approximately 1 CF handle layer (or slab) thickness greater, then the other knife.
So the Caly III is 1 CF slab thicker then the Delica, and the Sage is 1 CF slab thicker then the Caly III.
The length of each knife is also a bit greater on each, going from Delica, to Caly III, to Sage.
Now.. I need that CF Kiwi to come out!
