Love my EdgeHog edger I've had for a few years now. Does a great job and is nice and easy to use. I typically buy a new blade for it every season since they are relatively inexpensive, but I do wish they lasted a bit longer. I'm not chomping mine up against the driveway constantly or anything when I edge, and I honestly only edge every other time or two when I mow. But somehow these still seem to wear down a bit quicker than I'd like. Even so, it's pretty much the only option for the edger, and it still does a great job. Changing them is easy as pie, so no worries there.
