Thread: Finishing with slurry on Japanese naturals

I think that depends on how fine the slurry stone you used is. I think some people advise the use of a diamond plate to ensure that the slurry formed is 100% from the finishing stone. Whereas if you used a small piece of similar stone the slurry will be some mix of the slurry stone and the larger finishing stone. This is not so much of an issue if you are using a really fine (as fine as the finisher) slurry stone, but can be if it's not quite as fine as your base stone. There are also less variables when you use a diamond plate, since you know that the slurry comes 100% from the finisher so you're not wondering if the results are from the slurry stone or your stone.

I hope that all made sense.
