let me throw into the mix with my slurry use

I had no nagura (cotigura?) anyway, I had no slurry stone, so I was using a piece of broken Shumate razor hone.

It was red and made from aluminum oxide and turned all the slurry pink.

I've used coti slurry on an Arkansas (faster, finer cutting under scope)
escher slurry on a swaty (no real difference in scratches under scope)
BBW slurry on an Arkansas (no real difference in scratches under scope)

never mind......lol
