I currently sharpen with Norton waterstones and get great results. I used grinder when necessary, 220 grit when necessary and then 1000-4000-8000-strop.

My flattening stone is worn out as well as my 220 grit. I'm wondering if a coarse diamond stone can work for both flattening the 1000 and up as well as removing material when I need to regrind or set a camber.

Any recommendations on brand and grit?
