by Bowie, and at the same time created another based on Bowie's original design but with a sharpened edge on the curved top edge of the blade. Black offered Bowie his choice and Bowie chose the modified version. Knives such as this, with a blade shaped like that of the Bowie knife, but with a pronounced false edge, are today called "Sheffield Bowie" knives, because this blade shape became so popular that cutlery factories in Sheffield, England were mass-producing such knives for export to the U.S. by 1850, usually with a handle made from either hardwood, deer antler, or bone, and sometimes with a guard and other fittings of sterling silver. The James Black Bowie knife had a blade approximately long, wide, and thick. The spine of the knife was covered with soft brass or silver, reportedly to catch the opponent's blade in the course of a knife fight, while a brass quillion protected the hand from the blade.

According to reports of the time, Bowie used his knife to kill all three men: one assassin was nearly decapitated, the second was disemboweled, and the skull of the third man was split open. Bowie died at the Battle of the Alamo five years later and in death both he and his knife became an American legend. The fate of the original Bowie knife is unknown; however, a knife bearing the engraving "Bowie No. 1" has been acquired by the Historic Arkansas Museum from a Texas collector and has been attributed to Black through scientific analysis. Black soon had a booming business making and selling these knives out of his shop in Washington, Arkansas. Black continued to refine his technique and improve the quality of the knife as he went. In 1839, shortly after his wife's death, Black was nearly blinded when, while he was in bed with illness, his father-in-law and former partner broke into his home and attacked him with a club, having objected to his daughter having married Black years earlier. Black was no longer able to continue in his trade. Black's knives were known to be exceedingly tough, yet flexible, and his technique has not
