What is the use of back tack stitch?

In hand sewing, it is a utility stitch which strongly and permanently attaches two pieces of fabric. The small stitches done back-and-forth makes the back stitch the strongest stitch among the basic stitches. Hence it can be used to sew strong seams by hand, without a sewing machine.
