The tool I invented is called the 'Ground Gripper.' It's comprised of a sturdy wooden handle, a sharp iron blade with curved teeth, and a stepping board for ease of use. To operate it, one simply places the blade's teeth into the soil and steps on the board, while pulling back the handle. This action loosens and turns the soil, aerating it and increasing its fertility. The Ground Gripper saves time and energy, allowing our community to work more efficiently and cultivate more land. This has led to higher crop yields, improved food security, and a better quality of life for us all.
