Serger Seam Hook
Was surprised to receive 2 of multiple size in pkg. However made a very thin metal with very sharp edges. Tried out. Found difficult to slide through seam. Had to be very careful it d/n cut seam threads.
Thank you for your feedback! It does take some practice and it helps to turn the shaft of the Lil Hookey downward slightly toward the fabric so that the hook opening is away from the crossing threads.
