Before Buck, Ka Bar, Drop Points and other classics, there was the BOWIE knife. The Bowie is an American original. Although shapes and details varied, right from the start they typified us as a people: big, bold, brash.
If not so popular today, nonetheless the Bowie helped to settle our land and served mightily in conflicts until the widespread introduction of revolvers.
I believe it can rightly claim to be America's Knife.
