Lost knives; found knives
Got taught how to shapen a knife, the first one, on a stone.
It was amazing how much money I saved over the years, by not buying new and expensive knives, by sharpening the old ones. And shrapening the found ones. And that also involved the household knives for the Thanksgiving turkey and the Christmas ham.
A pre-sliced ham!!!!!! My knives would have been insulted. Sharpening knives became a side hobby.
