My grandmothers garden hoe had worn down to a nub when she quit gardening. No bigger than a spatula. I bet it had hoe’d hundreds of row miles of garden.
I use my Dads hoe that I inherited, it also was worn down like a spatula and is still sharp as a blade. Hoeing is not work - with a sharp hoe. You have to get at the weeds early when they are tiny. I can hoe the entire garden - roughly 10’ X 40’ in about 20 minutes, the hoe does all the work, just give the soil a “shave” pulling up the tiny weeds and loosening the soil too .
