i work for havana auto parts and i wouldn't trust our machine shop to sharpen auger blades, they do real good with a lot of things as ed mentioned, but they don't know a thing about blade angles. i've been there 10 years so i've seen the processes. if it is a chipper blade(serrated) you might be able to touch it up with a file,(that's what i do with mine) if it's a knife edge blade, good luck, i,ve seen many blades ruined by people tring to sharpen them when they don't really know what they are doing. i'm thinking i might just take my hand auger to the mile, i've heard bad things about the dirt and gravel clarity of the ice there..Mr. Ed said:I don't know where you guys are located but there is a blade sharpening place on South Broadway - west side of the road around the area where Milty was. It's across the street from a trailer place. They laser sharpen all kinds of blades - from lawnmower blades to chop saw blades to chain saw chains. Next time I drive by I'll try to get the name of the place.
I'm not sure if they do it, but there is a machine shop on Havana South of Alameda that may be able to sharpen things as well - they do wonders on crank and camshafts and I'm sure they have the tools to sharpen blades. East side of the road south of Havana and South of the car lots. It's where the dealerships get their machining done.
Sometimes I wish I kept better track of the names of the places I do business with :-[
