In Garcia v. Joseph Vince Co. (1978) 84 Cal. App. 3d 868, the plaintiff's eye was injured when an opponent's sabre broke through his fencing mask during a bout. He sued American Fencer Supply as the alleged manufacturer of the sabre on the theory that the sabre's tip was much thinner than a regulation fencing tip. Plaintiff's opponent and the school used blades manufactured by both American Fencer Supply and the Joseph Vince Company. Plaintiff, however, was unable to identify the sabre used in the bout, as the opponent used the blades interchangeably and all of the blades were placed back in the team bag after the bout. There was no evidence from which a person could reasonably infer the identity of the blade's manufacturer. (Id. at p. 873-874.)
