Commercial ("normal") corkscrew for right-handers.
Corkscrew for left-handers (= mirror-inverted version of the picture above).
Two pictures behave in a mirror image to one another if they match in all lengths and angles, but have different handedness. In order to get two such images congruent, either left with right or top with bottom must be swapped for one of them. This congruence can be achieved by viewing one of the images with a mirror .
