Claim:
A manual ceramics cutter, comprising a base with an upper surface for the support of the ceramic part to be cut, a longitudinal rail fitted parallel and above the longitudinal mid area of the base, and a moveable handle, carrying the disc cutter or disc tool for the marking of the area of the ceramic part to be cut, the ceramic part being supported on the base of the manual cutter, said handle having a longitudinal passage so as to guide it along the rail, wherein the handle has a cam vertically facing and contacting the lower end of the rail and assembled on a transversal axis, which is fitted to a positioning knob that according to its angular position determines the opposing arrangement of sections of differing heights of the cam with the lower end of the rail pressing against the lower end of the rail, such that said cam forms a variable height support point for the positioning of the handle against the rail and of the disc cutter or disc tool against the base, in a higher or lower position, keeping the same or a similar angle of inclination for the handle during the cutting of ceramic parts of greater or lesser thicknesses.
