Abstract: A rock cutting and trimming device comprising a C-clamp, a hydraulic cylinder, a sleeve, a shaft, a top tooth, and a bottom tooth. The hydraulic cylinder is coupled to the shaft, the shaft fits inside of the sleeve, the sleeve is coupled to the top port of the C-clamp, the top tooth is coupled to the shaft, and the bottom tooth is coupled to the bottom port of the C-clamp. Each of the top and bottom teeth comprises a cutting edge, the cutting edge of the top tooth faces the cutting edge of the bottom tooth, the hydraulic cylinder causes the top tooth to move vertically upward and downward, and the cutting edges of the top and bottom teeth are vertically aligned so that when the top tooth is fully extended downward, the cutting edge of the top tooth is parallel to the cutting edge of the bottom tooth.
