Kleinsche Flasche als Flaschenöffner

Das optimale Weihnachtsgeschenk für Geeks löst das Bierproblem:
The problem of beer  That it is within a 'bottle', i.e. a boundaryless compact 2-manifold homeomorphic to the sphere.  Since beer bottles are not (usually) pathological or "wild" spheres, but smooth manifolds, they separate 3-space into two non-communicating regions: inside, containing beer, and outside, containing you.  This state must not remain.
A proposed solution  Clearly the elegant course is to introduce a non-orientable manifold, which has one side and does not divide 3-space.  When juxtaposed with the beer-bounding manifold described above, it acts to disrupt the continuity thereof, canceling the outdated paradigm of distinction between interior and exterior.  This enables the desired interaction between beer and self.
Implementation The Klein Bottle Opener1 shown above is an example.  It is palm-sized, durably constructed in stainless steel, effective2, and blissfully ergonomic.
Q E D  You need one. 
 [1]  This sculpture is factory-finished with a heat-treated patina.  It's glossier and more golden than the hand-finished version, and is unsigned.
 [2]  Yes, it really works!
