Re: Grinding stones...

I realized that maybe I have found the best stones and a search for better might be like chasing a ghost. I'll probably try the 150 bamboo eventually but for now a belt sander wins followed by my bamboo 120 stone.

The naniwa Omura is becoming a well liked stone in my collection. It cuts fairly fast produces a nice working mud and refines its own scratch pattern rather well. It's not a beast like the bamboo 120 but does a good job for its price range.

I wish I had better things to say about the 60 grit Ume, it might work on carbon steels but for stainless it was a no-go. I still think its a flattening stone.

Hi Jason,

It's ok not to like stuff. :)

For those following,

Here's the omura: http://www.chefknivestogo.com/naniwaomura.html

Here's the bamboo 120: http://www.chefknivestogo.com/nubatoma1.html

what kind of belt sander do you use?

A harbor freight 1x30, its time for a new one though mine is a bit old and used.

I got your package today Jason. I didn't have a chance to open it but I'm guessing the contents are sharp. :)

Jason,

Yes it is OK to say what you think about stones. Saying you dislike or haven't found an ideal use for a stone is more than fair. Even moreso with naturals, sometimes a stone doesn't fit a situation, be it the sharpener's tastes, the steel he is working on, etc etc. Clearly no one stone answers all needs. I do find that this type of stone (60 Ume) is a good flattening stone, but not for all stones. For Shaptons it is miserable. For Choceras, Superstones and softer naturals, it's fine. But for real hard stones (Shaptons, Nakayamas, Oxuku, etc - not ideal. I think it is a good thing to help develop a collective consciousness about different stones and here conflicting and varied opinions are a good thing. I find I can 'lean' harder on the 60 ume than most stones and the higher pressure works well with this stone for me.

I kept with the microbevel on them like last time but used the han-han stone for the micro, it made them very sharp.

I did one full convex too, its my version of how it should be ground to perform as a convex blade should.

Good morning everyone. Regarding those low grit workhorses, such as the nubatama 60 and 120, when they do require flattening, what is the preferred method? I'm assuming most DMTs and Atomas are a no go for this task since they possess higher grits than the above mentioned.

I rub them together. For example, I used my 180 bamboo last night to flatten my 400 bamboo and my 60 Ume to flatten my 120 bamboo.

Thanks for the reply, Jason, I appreciate it. I'm considering getting a 60 or 120, and the next level stone I have in my collection is a 400, so I'd probably need to come up with another flattening option until I have multiple low grit stones in the arsenal.

Nice call, Jason! What you are doing is a very classical approach.
