Next time you want to sink rebar into the ground, don't pound on it with a hammer. Instead, chuck the rod into a drill and drive it in like a screw. (It helps if you soften the ground first by pouring a little water on it.) The rebar spins in easily and doesn't get bent or beat up from hammering. And if it hits an obstruction, such as a sewer pipe, you'll feel it before you break anything.
