Here are some of the handy ways I have used a crochet hook over the years:
As an emergency cable needle when knitting my Bernat chunky cable blanket.
To unplug the bathtub drain. Each bathroom in our house has a hook designated for this purpose
As a hairdressing tool, pulling strands of hair out of a cap for highlights.
To fix dropped stitches in knitting or for fixing a hole.
To help untie a tight knot.
To hide a snag in fabric.
To help turn a sewed tube of fabric inside out.
As a bookmark!
As an aul.
