Bare Knuckle Fighting Championship (BKFC) is the first promotion allowed to hold a legal, sanctioned, and regulated bare knuckle event in the United States since 1889. Based in Philadelphia, and headed by President and former professional boxer David Feldman, BKFC is dedicated to preserving the historical legacy of bare knuckle fighting, while utilizing a specifically created rule set that emphasizes fighter safety. BKFC will hold all of its bouts in a revolutionary circular four-rope ring, designed to encourage fast-paced and exciting bouts. The patented BKFC “Squared Circle” contains scratch lines, based on the Broughton Rules which governed bare knuckle fighting in the 19th century, and which requires fighters to “Toe the Line”: start every round face to face, and just inches apart.
