The tool includes a blade with a lower inclined portion and an upper upright portion which portions are interconnected by an intermediate portion.
The inclined portion is moved edgewise through the ground and lies at an acute angle to the vertical to lift soil lying above the inclined portion. The intermediate portion is located in use at or below ground level.
The intermediate portion may comprise a bend or the blade may be curved over the intermediate and inclined portions.
