What kind of grit do you use on a folder for cutting fruit, rope, plastic, cardboard, allround stuff?

Low grit for a bite or higher grit for Smoother operation? In both cases I like it shaving sharp, but what do you guys use? And what holds an edge longer?
 
Shaving sharp is fine for fruit, but won't hold that edge long.

Cardboard wants some tooth, some grab. Shaving sharp won't do that.

A 1000 grit edge will work well for both, and last well.
 
I concur regarding a 1000 grit stone. But this could vary with different stones and also the steel you are sharpening. I own quality budget steels for the most part (D2, N690, Sandvik varieties, 9Cr18MoV, Aus10 and similar). With adequate skill on a whetstone, 1000 grit can take you anywhere from toothy to slicey razor-like. Gotta get the feel for varying pressure and learning to use the stone in a strop-like fashion after sharpening.

True. I have shaved off of a 1000 grit stone (Shapton Glass). But I wouldn't try that with a 1000 grit diamond stone, and I wouldn't try it without the long refinement I did to get that edge.
 
Simple answer for a good all round working edge, 600-1200 grit. I have known plenty of hunters who did not go past 240 grit for their knives. A skilled sharpener can get any grit stone and get an edge to do most tasks. Hope this helps, another piece of advise, Don't Over Think It.
