Цитата:
The owner of the KA-BAR trademark, the Union Cutlery Co. of Olean, New York, began using the name on its knives and in its advertising in 1923 after receiving a testimonial letter from a fur trapper, who used the knife to kill a wounded bear that attacked him after his rifle jammed. According to company records, the letter was only partially legible; "ka bar" could be read, as fragments of the phrase "kill a bear". In 1923, the company adopted the name Ka-Bar from the "bear story" as their trademark.
