well not a pocket knife but you know how KaBar knives were named.

"Our name dates back to the early 1900's from a fur trapper testimonial. He wrote that while trapping, his gun jammed leaving him with only his knife to kill a wounded bear that was attacking him. He thanked us for making the quality knife that helped him to kill a bear, but all that was legible was "K a bar". Honored by the testimonial, the company adopted the phrase KA-BAR as their trademark."
