Not an example of the same thing, really. Nails don't need to be that hard. They're typically made from thin mild steel. If it's hard enough to be used as cutlery, demo it like every knife gets demoed. Slice up some tomatoes, chop roots, and see how it holds and edge. If it can still cut 2m slices, it's functional kitchen knife. You can cut a steak with the disposable softwood knives we already have.
