A “load*” indicating digital readout and micrometer positioners make it easy to get controlled, consistent breaks.
the digital readout as the clamping handle and breaking arm are adjusted. The GKM-2 is specifically designed to incorporate the “balanced break” method to produce optimum knife edges. Balanced breaks require equal lengths of glass on each side of the score, along with a mechanism that applies equal load to each side, resulting in a straight break. The GKM-2 also makes it possible to achieve consistent “slow breaks” desired by many users.
