Shear (10) at low inertia for continuous cut of a metallic sheet including an upper roller (20) provided with an upper housing (22) suitable to house and to constrain a corresponding upper blade (24) which protrudes radially respect to the upper roller (20), a lower roller (30) provided with a lower housing (32) suitable to house and to constrain a corresponding lower blade (34) which protrudes radially respect to the lower roller (30), the upper blade (24) and the lower blade (34) are suitable to come close to each other and to engage with the metallic sheet in a cutting position in order to cooperate with each other for obtaining the cut of said metallic sheet itself. The shear (10) include rotating stiffening means capable of stiffening the upper roller (20) and the lower roller (30) when the upper blade (24) and the lower blade (34) are close to the cutting position and also the rotating stiffening means are capable of not interfering with the upper blade (24) and with the lower blade (34).
