The A1, the S1, and the F1 are all made in Seki City, Japan, probably by the same outfit that makes Cold Steel's stainless fixed blades, judging from details in the finish, and the cordura sheaths for the A1 and (optionally) the S1. They show a lot of attention to detail, and the Japanese F1's are, in my humble opinion, nicer than the older German version. The folks at Fallkniven say that the VG10 steel starts out as Swedish iron.
LagaNet, by the way, is my source. They carry the whole Fallkniven line, including spare sheaths for those who want both carry options on the F1. Last time I checked with Fallkniven's USA distributor, they didn't carry the whole line.
