A high-speed shear for transversely cutting a rolled ship having a small thickness and including at least one blade provided on one of two oppositely located drums, and a controllable device for displacing the two drums between a cutting position, in which the strip is cut, and an open run-through position in which the strip can be freely advanced between the two drums, with the two drums being synchronized in their open cutting position by respective tooth elements provided on the two drums and engaging each other, and with the tooth elements being so formed that they insure synchronization in the open position of the drums when they engaged each other with, a large tooth backlash and engaged each other substantially backlash-free in the cutting position of the drums.
