Hi, I'm Mark Sullivan for Expert Village. Today we will show you how to build a privacy fence around your yard. Now this is a pretty main type of tool here. This is what you are going to use when you hit a rock. Basically you would just force this into the rock until it is broken or dislodged. This is so you hit the rock. So this is what I call a busing bar. So that is that tool. After you break the rock loose then you can go back in again with your post hole digger and dig the hole out some more.
