This is one of the coolest things that you can actually buy. It is a Klein Bottle Opener by Bathsheba Grossman. It is made in the shape of a Klein Bottle, a 3D representation of a single sided shape. And it opens bottles. It’s a 3D printed stainless steel sculpture that fits nicely in the hand, giving you just the right kind of leverage; an absolute pleasure to use.
But— and this is where we were caught off guard— there’s a second great, yet completely independent, kind of Klein bottle opener out there: the Beverage Tool by Klein Tools. Klein tools is quite truly (as they say), “the #1 choice among professional tradesmen.”
We happened upon this gem at Hand-Eye Supply, the Core77 store, while visiting Portland, Oregon. As far as we can tell, it was there because they like well-made tools, including those from Klein, not because they like mathematics.
The tool has convenient “Tip-Ident” mark in the shape of a bottle cap so you can quickly find it among other tools.
And now, dear reader, you know where to get a complete set of Klein bottle openers.

Which of course begs the question: what do you get when you open a Klein bottle?
I have had Bathsheba’s Klein bottle opener for a few months. Not only is it a terrific “what is it?”, but it is also the finest most ergonomic bottle i have ever owned.
My buddy with a degree in computer science and minor in physics did know what it was!!!
We have the Beverage Tool at our house and absolutely love it. It fits nicely on our magnetic knife rack too!
