Taking a note from knives of Japanese past, this garden tool may be the last one you'll ever need. It's made from long-lasting, heat-treated stainless steel. Complete with both a straight and serrated blade, the scooped back blade means you can scoop, dig, trench, and cut to heart's content. There's even inch markers on the blade for getting an exact planting depth, which can often mean the difference between a sick and healthy plant.
