Anything with the Kershaw name is a great knife. When you get them they are scarry sharp. All the knives with stainless blades are harder to sharpen than a good carbon steel, but when you buy one, get 2 and send me one.
from what I understand there are 2 kershaw brands, the USA made ones and the NOT usa made ones. The usa made ones are nothing short of kick butt. I have had one for years and its with me at all times In fact it was made in OCT 03 (http://www.countryknives.com/store/assets/product_images/K1670GRYBLK.jpg) thats a pic I borrowed. I love this knife. its strong well made and has less of a curve than the one shown above it the edge. I dont know what steel kershaw uses on these blades but it does well by me. I also understand that the usa ones have a lifetime warranty, where as thier asian made brothers do not. I think it might have to do with the fact that ken onion designed ones are all the usa ones. its late and my facts might be off. But I love mine and like i said its always with me.
I had the cheaper version, the Speed-Bump, and it was one of the handiest blade designs I've ever used. Yes, it was a pain in the butt to sharpen, but worth the trouble to me. I will own the Spec Bump some day.
