Restored a chef's 25-year-old knife today

Been sharpening as long as some of these kids have been alive, but this one almost got me. Not the steel — the trust. He watched me work the whole time, arms crossed, didn't say a word until I handed it back. Then he just nodded and went back to his station. Some days I wonder if I'm the hand or the blade, but that nod was enough. This one I returned.
