A vestigial organ in a power tool

We all know about vestigial organs in living creatures, such as the useless vermiform appendix that gives many people a bad time. These were useful in earlier releases of our body plan, but are now just along for the ride.

So here is a sighting of a similarly useless historical remnant in a Bosch power drill.

I refer to the rubber part affixed to the power cord near the drill’s grip. This well-designed part was very handy in the drills of our youth…

These keys were all too easy to misplace, so this was an excellent solution – as the vermiform appendix used to be when we were all eating leaves before we became humans and learned about chocolate and other delights.

The thing is, my drill came with the now common keyless chuck… so the key holder is totally unnecessary. At least it isn’t prone to inflammation…
