I do the same as Purplev and sometimes do a light touch up with a stone. Cheap bits are filed once and trashed but good ones can be sharpened several times (lightly).

I touch mine up with a fine diamond coated sharpener.
I don’t know how you could keep the cutting sections even if you tried to do more. I will have to ask my sharpening shop if they do it. They do carbide router bits so maybe they can to Forstner bits too.
