Answer: I wonder if you are talking about an "edger". This is a shovel-like tool that you hold vertically, then step on to cut through the sod. They usually cut down about 6". Although you should be able to find one at any local garden center, here is a mail-order catalog that I'm sure you'll enjoy: Landscaper's Supply, web site: http://www.landscapersupply.com, ph # 800-222-4303. And, though I do like grass, I prefer ground covers that you don't have to mow!
Good luck in your future career!
