Average grit for a regular honing steel?

They do not commonly come in assorted grits or textures, some are more coarse but that is from there manufacturing process, a steel only takes the burrs and rough edges off a knife, to sharpen you either have to use a honing stone/whetstone or buy a sharpening machine, but these should only be used for dull knives once every few month or 2 times a year.
