Compost aerator (Loughborough LE11)

This is to turn over the contents in your compost heap. How it works is below:
"How it Works: Insertion: You push the long metal rod directly down into your compost bin or heap. During insertion, the two triangular metal fins or "flaps" at the tip fold flat against the stem to smoothly plunge deep into the pile. Aeration: When you pull the handle back up, the two flaps spring wide open like wings. This grabs, lifts, and loosens the dense, compacted layers of organic matter, introducing essential oxygen into the core of your compost to speed up decomposition."
