The blade has a cutting edge facing forwardly toward the front of the trimming blade system. The trimming blade system has a comb provided with teeth which project forwardly toward the front of the trimming blade system and which overlap the cutting edge. Each of the teeth has an upper face, two lateral faces, and a lower face. The lower face of each of the teeth is joined to the lateral faces by opposite chamfered faces. ## Claims ### Claim 1 A trimming blade system having a front and comprising: a supporting plate; a blade; and a cover plate, the blade having a cutting edge facing forwardly toward the front of the trimming blade system, the trimming blade system having a comb provided with teeth which project forwardly toward the front of the trimming blade system and which overlap the cutting edge, each of the teeth having an upper face, two lateral faces, and a lower face, the lower face of each of the teeth is joined to the lateral faces by opposite chamfered faces to form a shoulder, each one of the teeth is tapered toward the shoulder and is adjacent to an upper face of the blade, and the cutting edge is positioned adjacent the shoulder. ### Claim 2 (depends on 1) The trimming blade system of claim 1, wherein the teeth are stepped so the shoulders form rearwardly directed shoulders against which the cutting edge is positioned. ### Claim 3 (depends on 2) The trimming blade system of claim 2, wherein each of the shoulders is provided with a shoulder chamfer. ### Claim 4 (depends on 1) The trimming blade system according to claim 1, wherein each of the teeth defines an elbow extending forwardly toward the front of the trimming blade system. ### Claim 5 (depends on 1) The trimming blade system according to claim 1, wherein the lower face of each of the teeth is flat, and wherein the lower face of each of the teeth is in contact with the blade. ### Claim 6 (depends on 1) The trimming blade system according to claim 1, wherein the lateral faces of each of the teeth extend parallel to each other. ### Claim 7 (depends on 1) The trimming blade system according to claim 1, wherein the cutting edge is elongated and defines a longitudinal axis, and wherein the lateral faces of each of the teeth extend parallel to each other and extend transversally to the longitudinal axis. ### Claim 8 (depends on 1) The trimming blade system according to claim 1, wherein the cutting edge is elongated and defines a longitudinal axis, and wherein the lateral faces of each of the teeth extend parallel to each other and extend perpendicularly to the longitudinal axis. ### Claim 9 (depends on 1) The trimming blade system according to claim 1, wherein the teeth are spaced from each other by an interval having a value between about 1 mm and about 5 mm. ### Claim 10 (depends on 1) The trimming blade system according to claim 1, wherein each of the teeth has a length having a value between about 1 mm and about 15 mm. ### Claim 11 (depends on 1) The trimming blade system according to claim 1, wherein each of the teeth has a width having a value between about 1 mm and about 4 mm. ### Claim 12 (depends on 1) The trimming blade system according to claim 1, wherein the number of teeth is between 10 and 20. ### Claim 13 (depends on 1) The trimming blade system according to claim 1, further comprising a spacer sandwiched between the blade and the supporting plate. ### Claim 14 (depends on 1) The trimming blade system according to claim 1, wherein the comb is provided on the cover plate. ### Claim 15 (depends on 1) The trimming blade system according to claim 1, wherein the comb is provided on the support plate. ### Claim 16 (depends on 14) The trimming blade system according to claim 14, wherein the upper face of the teeth defines a trimming plane, and wherein the cutting edge is comprised in a blade plane which is parallel to the trimming plane. ### Claim 17 (depends on 1) A razor comprising a razor handle and a trimming blade system according to claim 1, wherein the trimming blade system is provided with connecting means for connecting the trimming blade system to the razor handle. ### Claim 18 (depends on 1) A razor comprising a razor handle; a shaving head; and a trimming blade system according to claim 1, wherein the shaving head is provided with connecting means for connecting the shaving head to the razor handle. ### Claim 19 (depends on 17) The razor according to claim 17, wherein the connecting means comprises shell bearings. ### Claim 20 A trimming blade system having a front and comprising: a supporting plate; a blade; and a cover plate, the blade having a cutting edge facing forwardly toward the front of the trimming blade system, the trimming blade system having a comb provided with teeth which project forwardly toward the front of the trimming blade system and which overlap the cutting edge, the teeth are stepped to form rearwardly directed shoulders provided with shoulder chamfers, and wherein the cutting edge is positioned against the shoulders such that a lower face of the teeth is adjacent to an upper face of the blade.
