Just had a thought.
I expect someone would want to know why I was thinking about adding a 2K to the 1K.
There is some thought that when you are designing a progression you should focus on microns rather than grit. The idea would be to drop the micron size by 1/3 to 1/2 at each step. If I am not wrong 1K is about 15 micron and 2k is about 7 micron. So from Japan Tool suggests this then on to Aoto (which he estimates at 3-4K), medium finisher, final finisher.

I'm curious how much you save by having a 2k. Another stone, but maybe less time on each stone? It seems to me like an awfully small jump to be making though, I'm not sure how much the edge will change from 1 to 2k. I'm certainly curious...

If you look at the grit you might go 1000, 2000, 4000, 8000
That corresponds (roughly) in microns to 17, 8, 3, 1.
If you take the 8 (2K) out of there, you could make the argument that jumping from 17 to 3 looks pretty big when the next step goes from 3 to 1.
It makes a case that many of us take a pretty big jump (in terms of particle size) in the early part of the progression.
It also gives me an excuse to buy the Chocera 2K.
