Hand and Ox 46

When it comes to handling granite, there are three major challenges. The first and probably most

obvious difficulty would be freeing the blocks of stone form the ledge or the bedrock. The second challenge involves convertingthe blocks into the desired shapes and sizes of the consumers and thirdly, moving the granite to its final destination. Even to this day, a great deal of the work that goes into extracting and beautifying granite is done by hand. This hand method involves the use of a hand drill or a cross-pointed iron chisel, called a star chisel. This is used to drill a row of holes into the stone in which place a plug and feather (wedge-like system) is used to chip and flake of pieces of the granite. By placing a pair of iron pieces on either side of the wedge, the way the wedge meets the inside surface of the hole is changed, causing the pressure of the wedge to be distributed deeper into the stone. The combination of these tools will eventually cause the stone to split. This method of splitting stone was so effective that it continued to be a basis for quarrying, although there have been some industrial advancements.
