I'm not sure I'm following you here. There is a surface, which can be 
imaginary at first, which may not be static in time, that marks a 
boundary between where hydrogen and helium atoms are, and where they are 
not. Or conversely, a boundary between where atoms belonging to the 
alloy steel are, and where they are not. (Those two boundaries, by the 
way, may not coincide.)

I understand where you are coming from, but let's look it a little 
differently. Let's suppose that the metal of the fork is optically 
smooth, through some myopia. Then, despite the sharp tines, the fork has 
a 2D surface, with that myopic proviso. Likewise, a bunch of welded 
forks, despite a large number of sharp tines would have a 2D surface, 
with that myopic proviso.

So, now let's zoom in, not to the atomic level but enough to determine 
that the surface of the fork has a number of irregularities. In fact, 
there may be several dips and sharp points in those irregularities. But 
that's no problem, right, because we already established that at a 
higher level. At this level, having a number of "sharp tines" and 
concavities doesn't change the fact that there's a 2D surface, though 
still with some myopic proviso.

So now go down to the atomic level. Now there are lots of convexities 
and concavities, and in fact those are all moving around. So what? It's 
basically the same as what we had previously.
