The other day, a customer asked me to stock
a tire lever called TyreKey (brand name)
in the shop.
It's a tool (apparently) that makes it easier to install the second bead of a tire onto a clincher rim—after you've seated one side of the tire bead and inserted the tube, fitting the other bead can be really tight to do by hand. This tool supposedly lets you do it more smoothly while avoiding pinch flats on the tube.

The manufacturer posted a how-to video on YouTube,
but honestly, it doesn't seem like a tool I'd need.
I'm borrowing one from the customer to try it out,
and maybe I'll adopt it as a shop tool if it works well for me...

That said, there's another product out there with a very similar name
that has basically zero function as an actual tire lever,
so I'm posting this image as a heads-up
to make sure people don't accidentally buy the wrong one.
