It is a yellow paper back book, has a bunch of '76 info on Case knives, Cattaraugus, Remington, Winchester, then it has a long list of knife companies under a section titled "Price guide to knives in general". All that to say, there is listed a company named Depend-On-Me Cutlery Co., N.Y., U.S.A. The ND-ON fits this name. It doesn't list any thing about the knives other than generic values, good $8.00, mint $50.00.
Maybe a place to start that somewhat matches the clues you gave.
