This talk explores the historical, cultural, and technological significance of knives in Louisiana from the seventeenth through nineteenth centuries, tracing their evolution from French-Canadian trade items to iconic American weapons like the Bowie knife. Beginning with shipments of the Couteau Boucheron to France’s North American colonies around 1662, it examines how this European kitchen knife became essential to diplomacy, survival, and economic exchange in the Lower Mississippi River Valley, and concludes with the Bowie knife’s transformative impact on American history.
