Thread: Cross-border slurry?

I'm curious as to the community's experience with what I'm calling "cross-border" slurry - i.e. using a non-native rub stone on a native base stone to create a slurry. So for example: using a Thuringian rub stone on a jnat, or a nagura on a coticule or even on a synthetic stone, or vice-versa for any of these or other combinations. (I'm not talking about using different nagura on jnats in a progression.) Does anyone do this regularly? Any interesting observations? Apologies if this has already been discussed elsewhere (or if it's otherwise a ridiculous enquiry. . . ).

It may be worth saying that using Mikawa nagura on jnats actually fits your definition, While both are from Japan, they’re entirely different stones geologically speaking.

Sakimoto San, the owner of the Asano stamps (Mikawa nagura) also uses Mikawa nagura on synthetics, and it does smooth things up a bit. Try using a little koma or mejiro slurry up to 8k synth or so.

I know a couple of guys having used Thuri Slurry on 12k synthetic stones. It helps smooth out the 12k edge as it can be a little keen for some. This is not something new but it hasn't been brought up in a while. Saving used slurry to reuse can be done. But some stones the slurry has done its job and is not going to do much later.

I've read in a thread on here about a decade ago of someone using Thuri slurry to finish on a Jnat, for the same reason as the post above I believe

Sometimes it’s best not to over think things and just try it, lol!

For sure. One of my routines is using a midrange stone slurry. And dumping it on my finisher. No rules. Don't be afraid to try things.
