Air-assisted/manual Blockshear tools are self-contained and feature a unique operation that provides the highest productivity for splitting natural stones and masonry products in the industry. This block splitter is equipped with a Blockshear designed foot-lever. When the operator places the new stone or block on the worktable, the first time he presses the (single) foot-lever, the worktable and the lower cutting blade move up by about 2 inches. In one move he fits the upper blade snuggly against the material being cut. Subsequent pumping of the same lever drives the hydraulic actuator in 1/8-inch increments, until it quickly splits the material. Only Blockshear tools have this design feature. Sometimes called a block spliter, brick spliter, or paver break (brake) or paver splitter.
