Auger sharpening

[the pilot cock]

I've got one of the old Jiffy White Lightening augers. It's as old as the hills but it runs like a top. Last year I replaced the blades but it still doesn't chew through the ice very well. Actually it does a lot more bouncing and scraping than chewing. A buddy figures I need to get the center point sharpened. Could anyone suggest somewhere to get that done that might be quicker than getting into the queue at Lawn Mower Hospital or someplace where I'm waiting in line behind people getting major tune ups done... Or is there an individual who has the know how to do it. Not looking for free labor. I'm in Edmonton. Thanks!
