So for a touch up of an otherwise finely honed razor, you might just take 10 easy laps on the Chinese 12K, strop on leather, and see how it feels shaving.
I made the mistake of "touching up" on fast-cutting barber hones, where 30-40 strokes was a VERY bad idea.
You might pick up a cheap razor of one of the universally reviled brands noted on this site for about $10-15 just to work on the physical movement of stroking the edge down the hone and back without fumbling it.
If you take it slow and gentle, keep your stroke count low (increments of 10 simple X strokes) I don't think you'll do much harm to your razor on a Chinese 12K stone as long as you keep the blade flat on the stone with even, very light pressure. I think of it simply as stabilizing the blade on the stone, not even pressing it to the stone....kinda like a good shaving stroke!
