The overwhelming bulk of Buck Knives are made in the new Post Falls, Idaho plant. This includes: 110, 112, 100 series fixed blades, 300 series (black delrin inlays, not the wood), 500 series, Alpha Hunters, Rush, Tempest, Sirus, 172 Mayo, 55, 178 Adrenaline-Ti, Koji Buck knives, 525, 526, 425, 433, 436 Short Revolution, 281 and 282 NXTs, 450s, 442s, 444, Alpha Crosslocks, 691/191 Zippers and 692/192 Vanguards, 477 Caping, All Strider Bucks, 883 Crosslocks, 650/655 Nighthawks, 111s, 925s, 800 signature series, Yellowhorse knives, and the 970 dagger.
There is some work still done in El Cajon by Wilde Bill Cody on certain limited edition, special project type knives.
I may have overlooked one or two models but you can certainly see that only a small portion of the Buck Knives line-up is made off-shore.
