1. A block splitter device comprising first lower and second upper opposed block splitter assemblies,
the first block splitter assembly having a first end opposed from a second end, a first side surface opposed from a second side surface, a bottom surface, a central depression and exactly two first forming blades, the central depression extending the length of the first block splitter assembly as measured from the first end to the second end, one of the first forming blades being disposed to the right of and one of the first forming blades being disposed to the left of the central depression, the two first forming blades each having a single forming surface, each forming surface being horizontally planar and having first and second forming edges, each forming surface having a lateral width as measured from the first forming edge to the second forming edge, the lateral width of each forming surface having a larger dimension at the ends of the first block splitter assembly than towards the center of the first block splitter assembly, the second block splitter assembly having a first end opposed from a second end, a first side surface opposed from a second side surface, an upper surface, a central depression and exactly two second forming blades, the central depression extending the length of the second block splitter assembly as measured from the first end to the second end, one of the second forming blades being disposed to the right of and one of the second forming blades being disposed to the left of the central depression, the two second forming blades each having a single forming surface, each forming surface being horizontally planar and having first and second forming edges, each forming surface having a lateral width as measured from the first forming edge to the second forming edge, the lateral width of each forming surface having a larger dimension at the ends of the first block splitter assembly than towards the center of the first block splitter assembly, and the forming surfaces of the forming blades of the first block splitter assembly being opposed to the forming surfaces of the forming blades of the second block splitter assembly. |
