EZ-Digger - and that's pretty much exactly what it is. Although callling it the EZ-Grass-and-Weed-Ripper-Outer would be even more accurate. The little tool in my photo is something called a Cobra Head weeder, which I find it perfect for getting into small spaces between garlic and onion rows. Several gardening compatriots have complained that they don't know where I get these things so I hunted them down online and have popped a couple of links from amazon.com into this post.
