If our kitchen sink gets blocked, the best thing to do is to remove the u-bend and dig out the obstruction.
I can't do that with the shower drain, though. because it's under the shower tray.
Fortunately, the nature of the blockage is a lot more predictable in the shower, especially when family members have long hair.
I needed to clear the drain (again) yesterday, but rather than muck about with knitting needles and long-nosed pliers, I quickly created this little fishing hook from a large paper-clip (although any stiff wire would have done the job).
It was so quick, in fact, that it took a lot less time to make and use the tool that it did to write up this Instructable.
Such is life.
