What the catalogues say
The compost mixing tool allows you to stir compost material to let air in. Simply push the tool into the heart of the compost heap, twist and withdraw – as you do so the hinged flaps open, stirring the material.
Although not a complete replacement for proper turning of a compost bin/pile (emptying out and refilling) the stirrer does do a good job. It is especially useful if you cannot manage to shovel huge amounts of compost.
I have one for about 14 years and it is still going strong.
