Plenty of machines have the power to pulverize boulders, but who needs heavy machinery or a jackhammer when you've got a two-pound hammer and a chisel?
Sometimes the old ways are just as good if not better at doing things like bisecting boulders than the new ways, as Dennis Carter proves in this video shot at the Deer Isle Hostel in Maine:
The technique creates many small cracks that combine to eventually split the rock.
Dennis Carter, founder and owner of Deer Isle Hostel in Maine uses a 2-pound hammer to cut a 26,000 pound block of lovely Deer Isle granite into two equal parts. This is the first of many cuts. When finished, the resulting smaller blocks will be used to make the foundation of a workshop that he is building at the Hostel.
