Yeah, the process isn't even particularly difficult. I'm trying to recall where
a decent sharpening exposition is, since I'm only half awake. Try:

Easily sharpened with a file for the cutting edge, and a machinist's scraper
for the rim. Scrape only on the inside of the rim.
I wouldn't trust any old sharpening shop with them, but there is a shop that
offers Forstner sharpening on eBay. Know nothing about them.
Connecticut Valley Manufacturing (Convalco) is the original manufacturer of
Forstner bits, since eighteen-something. They offer a sharpening and
reconditioning service. Not sure if they'll do other brands, though.

A small diamond file and a steady hand renews mine,
quite successfylly.
My diamond file cost about $10 (DMT).
