I think I have come across a little too harshly in my review on the use of choil positioning of the index finger on the Sage. I really do find it comfortable when held that way and the control is great. Nothing wrong about it at all, though it still feels just a tiny bit foreign to me yet... something that will no doubt lessen and disappear with time and use.
I'm sure that for many users, those who are accustomed to using full-grip hold on knives, it can take some getting used-to to hold a knife with a finger on the choil, rather than completely on the handle.
My G10 Dragonfly most definitely has a choil-required grip and I've grown to like it very much as well. I do plan to add a Cat in the near future also, which also requires a "choil" hold. So I don't want to make too much of this point.
Bottom line for me with these two knives is that I really like them both quite a bit and feel both are good values at widely different price points. But I feel compelled to give extra credit to the Persistence for being such a stellar performer at such a remarkably low price. There is little that the Sage can do that the Persistence can't at 1/3 the price. One can speak to the merits of S30V, which are wonderful, but for the most part, my experience (albeit as a "light" user) is that 8Cr13MoV does a very good job for the average user and saves a lot of money. Same goes for the G10 grips vs. the more costly carbon fiber.
If I were to require a considerable amount of moderate to heavy use from a single EDC knife... I may find the Sage's S30V steel a great advantage, perhaps very well worth the additional cost. As a light-duty user, however, with a variety of different knives in EDC rotation, I don't so much require the advantages of S30V over 8Cr13MoV. But I'm very happy to have and use both the Sage and the Persistence.
The Spyderco knives I still can't warm up to (and I haven't bought a model with this yet - and may never do so) are those with FRN grips/handles/scales. The FRN may do a very good job functionally, but to me they just look a bit, shall we say, cheesy. For that reason, I am only drawn to purchasing G10 and CF Spydercos at the present time. Fortunately, there are plenty of wonderful Spyderco models available with G10 or CF scales, so my aversion to Spyderco FRN models isn't creating any problems for me so far.
