If you carry plywood of any size, or drywall, even if it's just once piece here and there, this is must have tool. For the price, get three, as they tend to disappear. I hade a steel one years ago, but somebody needed it more than I did. You simply have to put this in your tools that get a bit dusty from time to time, but when you must carry 4'x8'(12') panels, you will be grateful this cheap tool was in your arsenal. MUST HAVE tool !!!!!
