I’ve got a clone of the Gerber LST, it has “FEDERAL Ammunition” printed on the blade, and near the pivot it says Gerber 500 on one side and Portland, OR, USA on the other. I don’t recall buying the knife, not something I’d pay for; maybe it came with some ammo. Dunno. It’s right at 6 1/4” open full length, same 2.63” blade.

PS: It appears the Gerber 500 predates the LST -- so not a clone, similar but different, earlier knife.
