A manual cultivator tool including a handle, a U-shaped blade, a tubular member provided with spaced flattened end portions having similar intermediately disposed bends therein, and a pair of separate handle attaching elements assembled into a final construction in which the tubular member interengages with the free ends of the legs of the U-shaped blade to form a strong annular structure and the attaching elements provide for both connection with the handle and the annular structure in such a way as to effect a limited tilting movement of the horizontal earth penetrating blade portion of the annular structure.
