The U2 is the only LAMINATED folder using a powdered steel at present. I've had a fun, and very educational email correspondence with Peter. Fallkniven began using ATS-34, switched to VG-10, then the VG-10 laminate and in the U2 this combination. The choices in modern steels available compared to a few decades ago are almost mind boggling. I'm happy with Fallknivens. They are simple, razor sharp, off the shelf tools that work for a reasonable investment.
