It has already been said, but I will add my .02 or so.
I own probalby about 20 CS products. I have only ever sold one, a Trailmaster Bowie in SanMaiIII, which I used for 10 years, and sold when I stopped using it because I had a bigger nicer chopper.
I have only ever had one "failure" with a CS product. I recently bought a CS Black Rhino. I took it and carried it for a week or so, and the lock spring came loose, making the blade stop shutting all the way, and the lock up was not tight any more (because the lock spring had come forward from where it was supposed to be. I sent the knife back, and received a new one in the mail. It did take about 2 months or so.
The Axis lock they used earlier is a solid reliable lock, and I have one I have been using for 10 or so years.
CS makes some solid pieces for great value.
When you get up into their higher end knives, with the laminated steel, I might start steering you toward other manufactures at the same price point. Not because I don't love the laminated steel..........just the opposite. I love it. I love the the edge retention, and strength. What I don't love, are the Krayton handles. I have a few with that handle treatment that the rubber is too soft, and mooshy. Usually only after years of use and age. I wish they would switch to another handle material like Resiprine C, with more resistance to age/chemical/heat. That said, other manufacturers, who have stellar reps like Fallknives use Krayton on their handles as well.
Just shop the prices arround before buying.
I love their hawks for the price, and have even bought some crazy stuff occasionally (poll axe is one, I mounted it on a hickory pick handle and throw it).
If you see a design you like, buy it. Try it out.
The steel the use in some of of their knives is not super steel, like Aus8A, or Krupp stainless. But it has a good heat treat, and keep and edge reasonably well, and is plenty strong.
I am carying a pocket bushman a lot and just love the heck out of it, for the $30's it is a killer stong folder. Only improvement woudl be a better steel for the blade.
