Granite as been used as curbing for over 100 years and as you might imagine the technology to make curb has changed during that time period. The tools and techniques first used consisted of different ways to split the stone and then had work it so that you ended up with a piece of curbing. On some of the oldest pieces one side was left very rough because it was to be buried and would not be exposed, this obviously was a money saver. What makes an old piece of curb look “antique” is the wearing of the edges and face of the stones from cars and people as well as the hand splitting process when the curb was produced. In the last 50 years sawing technology has been employed and all “new” curb has a very smooth or sawn top look. Stone Farm harvests and reclaimed both kinds of curb ,but the material we like best is older, more worn and the hand worked techniques were used to make it.
