I recently acquired a 1000/3000 Suehiro SKG-27 Toishi combo stone. I know that it's a ceramic stone, it cuts very quickly.

Goodness me it is a great stone, but in truth, I've not much experience with stones... Can anyone offer any advice in order to get the most out of them?

I also have an Aloxite Barber's Hone (which is roughly 5K-6K grit size ~I think, maybe a bit less~) and an Escher Stone which is Blue-Green stone I'm pretty sure (being a natural it doesn't have a grit but would be around 13K-14K equivalent I've read). See this post for more info

I've been getting nice results but under magnification with a loupe (30x) I can still see some very very very fine (completely invisible to the naked eye) jagged edges. How can I get rid of these?

The razors will pass a HHT most of the time after they come off the stones and will pop my stray beard hairs clean off 7 times out of 10 but I reckon there is more to be found from these stones.

Thanks all, very much appreciate your help.
