The invention relates to a method for cutting a cast strand or intermediate strip (1) using shears (2). In order to facilitate improved rolling of the section having significantly reduced thickness, the method according to the invention has the following steps: a) bringing part of the completely solidified cast strand or intermediate strip (1) in the conveying direction (F) of the cast strand or intermediate strip (1) in front of the shears (2); b) placing a first blade (3) of the shears (2) onto the one surface (4) of the cast strand or intermediate strip (1) and placing a second blade (5) ofthe shears (2) onto the other surface (6) of the cast strand or intermediate strip (1) and performing a cut by carrying out a relative movement of the two blades (3, 5), wherein at least one of the blades (3) is in a pushed forward position; c) upset forging or upset forging with stamping a wedge-shaped contour on the end of the cast strand or intermediate strip (1) that is in front of the shears(2) in the conveying dire
