A thread cutter for an interlock sewing machine wherein the sewing machine has a small diameter cylindrical arm and the cloth being sewn is fed along the axis of the arm. A plurality of needles are disposed along a line orthogonal to the axis of the arm and an arcuated, movable member having a hook at its tip is pivotably supported ahead of feed dogs on the sewing machine relative to the line of feed. The arcuated, movable member is turned by means of an operative plate disposed along the axis of the arm and, in cooperation with a fixed blade, cuts threads after the cloth has been sewn.
