F keys

Most universities have both office specific keys and more general "master keys", I have observed a curious trend among those keys.

The "F" keys - those that open only the inner sanctum of faculty offices, closed seminar rooms and coffee supply cupboards - as opposed to the more general building keys, or keys for student offices - are "pointier", and this means they are far superior for opening bottles.

Using keys to open bottles, specifcially beer bottles, is an old survival skill from student days; particularly useful now that it is almost impossible to travel with tools, like bottle openers or swiss army knives. But, not all keys are the same, the best keys have isolated, or two adjacent "high points" with acute top angles.

So, that is fairly trivial; clearly there is a physical cause, something to do with the relative number of tumblers that needs to be lifted in the more closed locks than the open to everyone locks, but, the really interesting thing is that F keys at Private Universities (and you know who I am talking about...) are far superior to the F keys at State Universities (and you know who I am talking about).
That is interesting.

I don't know if this is by design, or some accident of Private Universities just buying better, chunkier locks with lots of tumblers and pins.
But, albeit based on a limited and preliminary study, I conclude that faculty at Private Universities are better equipped to effortlessly open beer bottles in emergencies, than are the poor faculty at State Universities.

More study is clearly required, and I am willing to do the work, even if I am a theorist.
Some funding is required though, for travel and supplies. I will also need volunteer institutes to entrust me with more F keys, or provide suitable faculty to lend the necessary time and equipment
