Good low grit stone for M390

Fri Jun 28, 2013 2:43 pm

Hi Mark,
I was hoping you could help me out. I have an artifex in m390 and was hoping you could recommend a good course some for it. I have naniwa stones in 1k, 3k, 8k, and 12k, and they treat me very well for maintenance but with the pm steel I am not able to set the bevel quickly. I saw the latte and it piqued my interest but before I bought it I was just hoping to get a recommendation for use on powdered steel. Would a chosera be better? Or a nubatama?
As always thank you for your time and dedication.
Sincerely, Scott

Try the Latte 400. It's a quick cutter and does a good job on this steel. If you want something more aggressive try the Nubatama 150 Bamboo. I like both of these.

Actually, diamonds would be the best bet....not necessary though.

Something like a DMT Coarse or perhaps (never used one) Atoma 400 would be great.

Other than that, the Beston is still my favorite coarse stone. Never used the Latte 400 though.

The latte 400 is a little slower than the bester 500, but leaves a much more refined scratch pattern, the bester 500 can leave nasty scratches that can be a pain to get out at higher grits.

I don't remember if I tried my Nubatama 150 on M390, but the Latte 400 and Bester 500 both worked well on it. Lately I've been thinning all of the M390's I have here with the belt sander and then sharpening up from there.

Most synthetics battle with M390....concur with Adam - go diamonds.
