A sewing machine, in particular a buttonhole sewing machine, is equipped with needle-thread-clamping scissors which have a lower half provided with a cutting edge at its tip portion. They further have an upper half pivotal relative to the lower half and having a cutting edge at its tip portion. Further, they have a clamping jaw to be pressed elastically on the tip portion of the upper half for clamping and holding a tail piece of a needle thread. The upper half can be pivoted in such a way that a receiving opening for the needle thread is formed in an opened position of the scissors, whereas, in a closed position, the needle thread is cut and the tail piece of the needle thread is clamped and retained between the upper half and the clamping jaw. The upper half can further take a third position in which the tip portion of the upper half is free from the clamping jaw and the tail piece of the needle thread is released.
