The rounding of the bevel that would occur just from stropping is trivial. It's much more likely after two months that the edge is just chewed up as you would expect after that time. A pasted strop will refresh it to some extent, and you could resort to that several times in succession. Eventually though you'll have to go back to the hones.

At that time, I'd try 5 to 10 LIGHT strokes on just the 8k, then strop and shave. If it's not good enough yet, then repeat it. If this fails to do the job, only then would I suggest a minimal pyramid. In general the 8k should be sufficient by itself unless you have really worn it out.

When to touch up the edge? When you notice a diminishment in the shave.
