My grandfather was a digger, not a detectorist digger, but a laborer. He was not a wealthy man but would volunteer to dig the graves of recently passed as a token of sympathy to the family. He dug many wells and cisterns by hand. He had firm beliefs about shovels and spades. One of which is a good shovel only cuts when it's clean, AND a good shovel only cuts well if it's sharp. He always dipped his shovels in a bucket of used motor oil after he cleaned them up. I just re-sharpened my digger yesterday. Did it need it? Absolutely not. Did It make me warm with nostalgia and make me smile when done? Yes.
