What can be said about the Kershaw Skyline that has not been said before, nothing really besides I seem to be addicted to them, considering I currently own 4 versions of it, and maybe 15 have passed through my hands. The Skyline was the first quality modern (one hand opening, locking, single blade) I bought, and that was maybe 8 or 10 years ago.
It may just be the best light duty, American made, EDC for under $50. The key word being light EDC, it is not a heavy duty folder, I've seen many people complain about breaking the tip off while using it as a pry bar, which some knives maybe able to do, but the Skyline is not meant for. The benefit being, it is a very thin edge, it cuts very well, and has a good sharp tip. It's light, slim, and a good size that is people friendly.
And, being such a popular knife, many after market handles and parts can be found for it. Such as the Ti scales in the 3rd pic.
