Custom bent to fit the user and sharpened like a knife. Also sharpened on the sides. The little bat wing hoe is cool but the source he mentions wants over $100 for one. I'll make my own for that price.
Go medieval on them weeds.
My favorite hoe, aside from the one my Grandpa left me, is the Korean Hand Plow. ('Ho-Mi') Comes in short and long handled versions. Goes through the toughest of soil like buttah!
I would buy one of those if I were a few years younger!!!
I like Danny and Deep south Homestead. He runs a serious small farm!
