Lowest grit stone needed

Hello.My current lowest grit stone is an ume320.I also have an Atoma 140 for flattening. Do I need a lower grit stone for chip removal?

Absolutely not.

And your Atoma is MUCH more adept at grinding knives than flattening stones. IMO, spending $125 solely to flatten a stone is money poorly spent. IF you have such dramatic chipping and such limited time to repair it, use the Atoma. A 320 does the same that a 140 does, it just takes incrementally longer to do it.

E.g., Atoma 140 chip removal: http://www.chefknivestogoforum.com/kanji-id-t1281.html

Thanks for the answer. Never thought that the atoma can be used for sharpening. Have always used is as a flattner. But I live my ume 320 so I will use it for chip removals and exrreme thinning.

NORWAY <> There are many of whom solely use Diamond plates for sharpening. A soft lap on an Atoma 1200 or DMT XXF produces an impressive edge. Diamond plates are multi-function tools that are just as, if not more, adept at sharpening knives - particularly wear resistant steel, than they are at flattening stones. If I intended on using a diamond plate solely to lap stones, a CKTG diamond plate would be a more cost effective route. Yes, the Atoma is more effective in that application, but not 4 or 5 times more effective as it is in price.
