Which folders are made in the US? I can only find one in the current hard copy catalog, the 4-Max. It also lists at $599.99

The prices on the rest are comparable to Spyderco's US made models, that would be ok except that they're made in Taiwan. Taiwan isn't bad, they do a great job on Spyderco's more "premium" folders. My best guess is Spyderco does these in Taiwan with better materials because the US would cost twice as much. These are usually carbon fiber and titanium, I see none of that in the hard copy I got.
I can get S30V G-10 Para Military 2s and G10 Manix 2s from dealers at a high of $120(DLC PM2) to around $85 (Satin G-10 Manix 2). The Satin Military is around $140 while the DLC version is around $150. They're all made in the US and the highest MSRP of the bunch is $279, less than half the cost of the 4-Max.
Like OP, I'm a little disappointed. I was so happy when my catalog showed up, after seeing the prices and country of origin I was scratching my head. I'll probably still get the American Lawman with the new steel to match my old one. It's my favorite design and size but that might be it. They even disco'd the medium Voyager, another favorite of mine. I was hoping for more US made folders but charging US made prices for Tawian folders that don't include titanium or carbon fiber like other companies offer is going to keep me from buying more Cold Steel folders.
