[INJ] That would be a cheese plane, then? They do exist, mainly to take molecule-thin slices of rubbery Dutch cheese of the right size to fit on a piece of bread. BTW, what's a cheese molecule properly called? I genuinely don't know. Cheesium?
(pen) There's every molecule under the sun in cheese (maybe not uranium hexafluoride) and some of them are quite big, like vegetable fats (50-55 carbons). On the other hand some are quite small and volatile like butyric acid, the smelly feet pong.
