Tom- I've not done my own sharpening but here in Rochester there's a guy who has sharpened my (and other's) frame cutting tools. I can share the contact if you're interested. At one time Jim Kish (sp?) offered cutting tool sharpening (perhaps was called "the tool grinder"?). At one time I read that Park offered sharpening for their tools, unsure if they would do other brands (doubtful IMO).

I will add that machining down a head tube face is more time consuming than I would like. I will grind down and rough file the face first (I use a square placed on the face with the blade running along the HT for eyeballing) to reduce the time spent turning the facer/reamer handles. A crown race seat cutter takes even longer... When I got a second 1 1/8" headset race cutter I had the local guy open up the diameter a tad and change the tool's rake to make the cutting go faster and also to reduce the final to spec cutting to not take off too much (I found that if I ask the cutter to reduce the diameter by a lot, like a raw crown comes with, the tool can remove just a hair more than ideal).
