A cutting guide (1) with a sagittal guide plate (10) is made available for generating an outer contour on a bone in order to apply a joint endoprosthesis (70), in particular a femoral component of a knee endoprosthesis. The cutting guide (1) according to the invention can be oriented relative to the bone and has at least two sagittal guide slits (12) for guiding a bone-cutting tool, wherein the sagittal guide slits (12) extend through the sagittal guide plate (10) and are arranged at an angle to each other.
