I needed something to break up concrete and remove old 4x4 fence posts. At depths close to 3 feet I needed something longer than my 12 inch hand chisel. While not specifically designed for a hand chisel, this device helped. However, I ended up with a 72 inch shovel designed for digging around posts. These shovels looked flimsy on the line, but the one I used was actually pretty solid and worked really well as a long chisel.
