Well, I've had the stretch for a few weeks now and it's a great knife! The CF handles have an awesome texture, kind of like sandpaper or a nail file but not as abrasive. The opening action is very smooth compared to my old Endura and locks up nice and tight with no wobble in any direction. I also like that the back of the blade matches up with the handle when closed, instead of having a sharp edge like on the Endura. I like how they maximized the working edge to handle length ratio. So many of Spydercos have finger grooves right up on the blade! It seems to me that that is not only a waste of blade length, but also potentially dangerous in use. The stretch has some kind of finger groove, but it's pretty minimal. This is a great knife for opening and tearing down cardboard boxes. All of the reviews made it seem like the blade is too thin, but I think this is going to be fine for my main hiking and camping knife.
On the downsides, the stretch is a bit on the heavy side and the blade is ever so slightly off center. I am also not sure what will happen to the CF when I eventually drop it on some rocks. And due to all of the curves, it's about as attractive as a...pelican?
Overall, however, I am rather pleased with the stretch. I think it's a great buddy to the small sebenza.
