I purchased the T2 while on a recent visit to the US. Also bought the Spyderco Military (S30V blade, G10 scales, without liners).
The T2 has the full grind blade and the black carbon fiber (zytel?) scales. I have not had the opportunity to test the knives to any degree but I have handled and carried both. I do not think you will have a problem with the 'grippiness' of the T2 scales. Reasons: I wet the knife and tried using it. While any wet knife will be less 'grippable' it will not slip from your hand - just hold it tighter (chuckle - sorry). But, my main reason for confidence in the grip is that the scales are just that - scales. They do not envelope the knife handle like the BM Griptilian for example. The liners are thick and strong and the handle is quite square and has gripping serrations. All this adds up to a knife that sits firmly in the hand. I like the T2 as an EDC (tip down, 4 inch blade, strong lock, deep finger choil, stromng build, S30V blade, cuts cleanly etc). Downside is silver (matt finish) clip which is easily visible in work trousers. It does not exude any panache, but it is an excellent basic EDC.
Slightly off-subject, but someone brought up the Spyderco Military, I am not too confident in the lack of steel liners, but then I understand that this knife was designed to be light enough for a soldier to pack along with all his/her other kit and was not intended for 1st line self-defence. For civilian EDC I am a little concerned about the strength of the knife, but then I felt the same about the Glock pistols when they first hit the market.....
You won't have any regrets about the T2 - it's a great knife.
