Their marketing is silly, but their products are genuinely high quality. I've owned many CS folders and also a Kobun fixed blade - all of which were of astoundingly high quality for the price. I'd recommend the Lawman, Code 4, and Tuff Lite - with a little searching, you can pick those up for a song and have a knife that is cheap enough that you can abuse it without hesitation and sturdy enough to stand the abuse without issue.
I highly recommend their products, despite my steel snobbery. Their AUS8 is exceptionally well done, and seems to hold an edge (in my personal experience) as well as most 440Cs I've used. You can pick up a good and sturdy CS for roughly the price of a Tenacious and have a much more robust folder.
