A cutting device and corresponding method for cutting a relatively rigid material), such as for example paper, cardboard, plastic material, composite or other. The cutting device includes a first cutting disc sharpened along its peripheral edge and rotating around its a first axis of rotation. A second cutting disc, also sharpened along its peripheral edge (and rotating around a first axis of rotation (X), is disposed in front of the first cutting disc with respect to the material and is co-planar with the first cutting disc (). 111. A cutting device for cutting a relatively rigid material () , comprising:{'b': '2', 'a first cutting disc sharpened along its peripheral edge and rotating around a first axis of rotation (X); and'}{'b': 19', '21', '3, 'at least a second cutting disc () sharpened along its peripheral edge () and rotating around a second axis of rotation (X), and'}{'b': 19', '14', '11', '14, 'wherein said second cutting disc () is disposed in front of said first cutting disc () with respect to said material () and is co-planar with said first cutting disc (),'}{'b': 14', '19', '12', '11', '16', '21', '14', '19', '12, 'wherein said first cutting disc () and said second cutting disc () are mobile individually or together, with respect to a support plane () on which said material () to be cut is to be rested, so that a distance between the peripheral edge (, ) of each of said cutting discs (, ) is selectively adjustable with respect to said support plane ().'}21914. The cutting device as in claim 1 , wherein said second cutting disc () is sharper than said first cutting disc ().31411161922. The cutting device as in claim 1 , wherein said first cutting disc () has a first diameter claim 1 , a first thickness (S) and a first cutting angle (α) of its peripheral edge () claim 1 , and wherein said second cutting disc () has a second diameter claim 1 , a second thickness (S) and a second cutting angle (α) of its peripheral edge.4.
