I have an all-nickel-silver table knife, the old style with the straight, parallel edges and half-round tip, that I would guess is around a hundred years old because of the design and the material. I use it almost daily to spread mustard, peanut butter, mayonnaise, etc.
I picked it up for fifty cents in a Goodwill thrift store, and wouldn't part with it for anything. I remember seeing them when I was a boy and they were already old and worn, and I'm past eighty.
My Grandmother's daily use silverware was a set like that. Wish I had kept it.
