A rock cutter for splitting stones is disclosed which shows a support surface for holding the rock and a first blade and a second blade which may be positioned to hold the rock between the first and second blades and on the support surface along with a means for moving the first blade towards the second blade. The means for moving comprises a hydraulically driven piston having a piston arm to which the first blade is mounted. The rock cutter also has a cover which is used in conjunction with a means for receiving pieces of the rock after the rock is split.
