Sometimes referred to as a Compost Turner or Stirrer. The 'T' shaped handle is by far the best as it greatly reduces wrist and shoulder strain so often associated with 'L' shaped/single hand models. Powder coated steel construction. Simple to operate, push directly into the compost heap and as it is retracted the 'winged' blades open and create pockets inside the compost, aerating as it goes.
Much easier than forking over and far less back-breaking!
