Hello everyone!
I mostly use the shapton 320 and Atoma 600 to sharpen my dull knives. I mean dull dull.

Sometimes just out of curiosity, after reaching hair cutting sharpness, i jump from the Atoma 600 to a Shapton Rockstar 1000. Thats where i f. up everything. I swear i hold the knife in the same angle.. Why is that?
Not even paper cutting. After some anger, going back to the Atoma 600 i can reach the hair popping sharpnes.

P.S.: I sharpen freehand.

Tl; dr: Want to use diamond stone as a flattening stone but also want to sharpen half dull knives. 1200 or 600 grit.

Hello everyone. Im not new to this hobby but wouldnt say old at all. But i'm new to diamond stones. I heard they are a lot better and don't deform like other whetstones.

Currently im using a 360/1000 grit whetstone. Which i overused a little and has these up and downs in it. Its not flat anymore, makes sharpening hard.

First of all i want a diamond stone because its not that messy (water). Second i need a flatening stone.

At home we cut a lot of pig meat which means sometimes we hit bones. The knives can dull out easly from that. But not NO CUT dull but dull. I hope you know what i mean.

So my question for these type of knives which grit is better when talking about diamond stones? Specially ATOMA 1200 and 600.

Thank you for you patience and answers :)!
