I would want to check out 1 and 2 for myself, before I'd make any commitments. 3, I'm sure that the plastic is durable.4, up to preferences.
I don't own a T2, but I do own a T4, so I'll try my best to answer your question based on my experience with the T4.Thickness: Yes, it's not as slim as a SAK, but even the T4 doesn't feel awkward during pocket carry in my opinion (but my favorite SAK is a Swisschamp, so I'm used to carrying a thick pocket knife).OHO knife: the knife isn't the easiest to open with one hand, but after a bit of practice it's doable. My biggest fear is that it would snap back halfway during opening when my thumb slips off while having one of my other fingers gripping around the knife (it takes some practice to keep your fingers away from the knife slot).Plastic: bothered me at first, but feels very durable, and even good in hand while handling the knife.Looks: The more I see it, the more I like it. By now I'm a fan of the look, it looks good on pics as well in my opinion.As always, just my own humble opinion (on the T4).(Image removed from quote.)(Image removed from quote.)(Image removed from quote.)(Image removed from quote.)
Of all the names...that Free get me all the time!

Longer and thinner, clip rides good,tip of the blade faces up, no snag points other than the blade lock tabs but the body of the handle is tapered past them. Only negative ive seen so far with K2 is no flipper blade launcher lever on the jimping part of the handle, you have to use the thumbhole. This is a good solid tool, no blade wobble etc.You can "feel" the pocket clip if tightly gripping the knife, not really a hot spot or pinch point, just a pressure into your palm.
Hollow Sabre grind will make a big (negative) difference for cutting your apples if that is relevant.
