The Cobrahead is my current favorite tool. I used it to 'denude" a 4x8 foot area in a very old lawn. It grabs everything in its path. With just a downward motion and a pull backward you get a good swath of (in my case) grass and thatch. If you have rocks, it gets around rocks; if you have dandelions, you can yank them out, if you want to stir up soil, or plant bulbs it's good for that. It's a "go to" garden tool.
