I used to have a similar weed puller gadget. It was just the long handle, and then kind of a forked prong on the bottom. It would slide into the dirt and cut off the weeds right at the root, and then you could just flick it out of the ground. After the weeding, i went around picking up the dandelions and other weeds that i had gotten out of my lawn.
Now, I happily look for the dandelion plants and harvest them for my greens ! I have read about how nourishing that they are, and when you get them before the summer heat sets in, they are not nearly as bitter as after the hot days of summer arrive. Even plain old lettuce gets bitter once the days are so hot and dry.
I pick the dandelion leaves, and since they are bitter, I mix them with a mild green, like collards or spinach, and it adds an interesting flavor.
I have some dandelions that have blossomed and gone to seed already, so yesterday, I took some of the fluffy seedheads, and scattered them into my greens garden. Then I will have them right there where I am watering daily, and since they are perennial, I don't have to plant them every year.
