I have three of the old blue American Anglers. One has been used for 15 years or longer and is still going strong. (I did buy new blades about 2 years ago) One has been at the shop for about 10 years, and the last one has never been out of the package (found it in the camphouse cupboard about a month ago!)...... My father thought there was no such thing as too much of a good thing. He bought these knives and stashed them all over the place.
