The design is the main reason you'd want one. Something like a ZT 0551 or 0560 will have better steel, better ergos, better customer service, better quality control, and better reliability, for about half the price. You won't have the problems with the thumbstud falling out or the blade beginning to play after a few months like Striders do. The ZT will also be thicker (sturdier) and have a Ti liner on the G10 side, and in the case of the 0560 ball bearings and a flipper. But knife buying is never about directly calculating the value of the knife based on its features; people buy designs that appeal to them. If the Strider SNG seems like the perfect knife for you and has that psychological "pull," then it's probably a justifiable purchase. If you're buying it because you think it has the best features in knifedom, look elsewhere.
