Course Stones

I'm still using a 150 grit diamond stone I got from Jon to do most of my repairs. I'll use my 2"x72" grinder for cheaper steels when I need to do a lot of thinning. Follow up work is really quick, even with 150 grit, when I pair it with the 800 grit diamond ceramic I got from Jon as well. I don't thin too much though, as the main concern in my city is just finding someone to sharpen a knife. Amazing that I'm the only one doing it here, and teaching people about how their knives need to be cared for is an ongoing process.

 

you having fun with the 800 grit one? I swear its my most used stone by a long margin

 

I'm having a lot of fun with it, though I don't use it with super cheap stainless knives. It's too easy to work up a burr, so instead I use a king 1000 to finish off those. For everything else though, it is the stopping point before I go to the 6k diamond from you.

 

I have found Nubatama course stones to be pretty worthless from using a friends. They glaze over very easily and are near impossible to flatten or recondition the surface when glazed. The 140 grit Atoma is as coarse as I use and 220 is the coarsest synthetic I use. This seems to work for all my repairs and needs. Don't see a need to go lower than the 140 Atoma.
