  • Post hole digger
    Patent number: 8888153
    Abstract: According to one embodiment, an apparatus includes a pair of shaft portions each comprising a handle slidably coupled to a base. Each handle includes a first impact surface and each base includes a second impact surface. The handles are slidable relative to the bases such that the first impact surfaces of the handles impact the second impact surfaces of respective bases. The apparatus also includes a pair of blades each coupled to the base of a respective one of the shaft portions to form respective halves of the apparatus. Further, the apparatus includes a pivot connection that pivotally couples the halves together at a location between the bases and blades of the respective halves such that movement of the handles away from each other moves the blades toward each other, and movement of the handles toward each other moves the blades away from each other.
