I have one, and it is my only Kershaw so far... I hope to get a Blur with the s60v or sg2 blade steel soon. The Needs Work is great, sharp out of the box, easy to sharpen, and the polymide handles have a good amount of grip. I disabled the speedsafe, and it makes a great manual flipper. My main beefs with this knife are the pocket clip and the hollow grind.
The hollow grind is good, but I prefer a flat grind. Nothing really wrong with the hollow grind, it's just personal preference.
The pocket clip is both a pro and a con. The bad part about it is that it is short and stiff when it's new. Too stiff for the length. The good part about it is that after use, it loosens up a tiny bit, so it is just about perfect. I like the length of this pocket clip because it makes the knife more discrete.
