The Switchblade Hoe has an adjustable-length aluminum handle that allows individual customization to help minimize both strain and back pain. Its interchangeable heads include two stirrup blades (3 and 5 inches wide) that flip back and forth with each forward/backward stroke; and three wire-hoe loops (2, 4, and 6 inches wide) that are designed to remove weeds right up next to the plants. Changing heads involves a steel connector with pins and clips (no tools required).
