Abstract:
An excavation tool having a lever with an end adapted for receiving force from a user's foot, an excavation head mounted to the other end of the lever, and a fulcrum mounted on the lever at the upper end of the excavation head for resting against the soil surface. The excavation tool may also have an excavation head for insertion into the soil with an upper end adapted for receiving a user's foot along the centerline of the excavation head, and a lever fixedly mounted to the excavation head, having an end adapted for receiving force from a user's foot. The excavation tool may have an opening above the upper end of the excavation head for receiving a user's foot on the upper end of the excavation head along the centerline of the excavation head. A fulcrum may be mounted on the lever at the upper end of the excavation head for resting against the soil surface.
