Everyone's different, it depends on so many things.
On most of my stock removal knives, I use 60 to rough, 120 to convex (both ceramic) then go to gator belts on a soft platen- 160m, 100m, 65m, and a scotchbrite maroon to finish.
For the handles, 36 to rough, 120 x then 120 y weights, 320 j-flex for a comfortable working finish. That's ten- then for sharpening I also use finer Norax, 45m and 16m to finish and a 5m to deburr.
I run my production line with these 13 belts- I go through lots of everything low grit and pitch em when they get clogged, but the gators and norax, they just don't wear out that fast.
