This Fiskars garden knife is four tools in one! It's a weeder, bag opener, sod cutter, and, most importantly, and trowel. It cuts with its serrated edge and has a straight edge to act as a standard garden trowel. If you don't want to disturb the dirt too much, there's a notched tip to remove weeds. All of this comes together with a non-slip, comfortable handle so that you can go about all your gardening with ease.
All this plus it's covered by a lifetime warranty. Once you use it, you'll never want to be without it!
