Wow! My grandfather knew and used such a person. He sharpened items like knives, shovels, axes, etc, and the sharpened items were kept in buckets of sand saturated with used oil. Good memory for some reason.
Lots of medical/dental tools get professionally resharpened, so there are people who do it. Ask a dentist, especially an older independent one.
“...He sharpened items like knives, shovels, axes, etc...”
Growing up my next door neighbor (these are beach houses so not occupied year around) would come to his beach house, every time he visited the small, ugly little Italian (though a very nice man to me) would go to his garage, clamp a shovel into the vise and sharpen it with a file. He would do this repeatedly and very much enjoy the activity (his tongue would come out between his lips...). He apparently carried lots of shovels in the trunk of his car.
His wife was a young blond ‘bombshell’ with 150 pairs of glasses. Once he invited me into his bar area for a soda (I would mow his lawn in the summer).
You could not believe the 100’s of 8 x 10 glossy photos in the bar. Mr ‘D’ (we will call him) was with virtually every BIG Hollywood actor/actress and every US President (this was in the early 70’s). Pretty impressive for a small, ugly man.
The next year I learned that he was the head of the PNW Mafia.
Then I understood the shovel sharpening...
