On Order! It is black and marked by a small triangle in the accessories catalog.

The BERNINA Hook combines the advantages of the two best hook technologies in a unique way. The new centerpiece from BERNINA has an innovative, centrally positioned drive that allows the BERNINA Hook to operate very quietly and smoothly. Two oscillating cams ensure smooth passage of the thread and extremely quiet operation at speeds of up to 1,000 stitches per minute and a stitch width of up to 9 mm.

The BERNINA Hook bobbin holds 70% more thread than standard bobbins. That means more sewing and fewer interruptions.
