Circumcision device, including a support (10), a rest part (20) comprising a stem (21) and a shearing template (23) arranged fastened on a distal end of the stem (21), which has a concave distal surface (23a) and a side surface (23b) tapered in the proximal direction, and a pair of arms (30, 30') each having a distal end provided with a semi-circular blade (32, 32'). Each arm is rotatable around an axis perpendicular (y, y') to the extension direction of the stem (21), between an open position and a shearing position wherein the semi- circular blades (32, 32') are closed to form a ring perpendicular to the extension axis of the stem (21) and have a cutting edge (33, 33') that engages the side surface (23b) of the shearing template (23). The rest part (20) is removably fastened to the support (10) and the semi-circular blades (32, 32') are removably fastened to their respective levers (30, 30'). Each lever (30, 30') is provided with a guide (31a, 31a') to determine the orientation of the respective semi-circular blade (32, 32').
