It's the Barlow, hands down. No other pattern comes close in having the documented history of use and popularity as the Barlow. And it was the Barlow pattern that really started the modern popularity of knife collecting when a columnist with the Louisville, Kentucky, Courier-Journal started a club in the 1950's called the "Barlow Bearcats". This is detailed in a reference in one of the other responses.
Let's face it, when you're asking about stuff that's "original American" it's tough to beat something that Mark Twain wrote about,
"Mary gave him a bran-new "Barlow" knife worth twelve and a half cents; and the convulsion of delight that swept his system shook him to his foundations. True, the knife would not cut anything, but it was a "sure-enough" Barlow, and there was inconceivable grandeur in that - though where the Western boys ever got the idea that such a weapon could possibly be counterfeited to its injury, is an imposing mystery and will always remain so, perhaps."
- The Adventures of Tom Sawyer
"All the stores was along one street. They had white domestic awnings in front, and the country-people hitched their horses to the awning-posts. There was empty dry-goods boxes under the awnings, and loafers roosting on them all day long, whittling them with their Barlow knives; and chawing tobacco, and gaping and yawning and stretching - a mighty ornery lot."
- Adventures of Huckleberry Finn
I gotta go for the Barlow.
