A stitching apparatus having:

• a sinker bar;
• and
• a sinker finger having a fixed end and a free end and a first and second lateral surface thereon, the sinker finger being attached at its fixed end to the sinker bar;
• wherein the improvement comprises:
• the sinker finger being recessed adjacent to the free end to define a depression in one lateral surface thereof;
• a first cutting blade having a free end, the free end of the first cutting blade being receivable within the depression in the lateral surface of the sinker finger;
• and
• a second cutting blade, the second cutting blade being reciprocably moveable with respect to the first cutting blade, such that a loop formed on the sinker finger is advanceable onto the first cutting blade and is thereon severed by the cooperative interaction of the first and second cutting blades.
