im not from the hat, but a quick google found a few sharpening companies, though i think they mainly do scissors and knifes for hair stylists and kitchens, but its probably worth giving them a call. i tried to sharpen some old rusty blades recently but it didn't help much so i just ended up buy some new ones for like 34 bucks at canadian tire.
Thanks, I have found a fellow in Redcliff that does sharpen auger blades and does a fine job, he is also making a set of custom blades for me as well. The price is $5.00/blade. I have an Ion 8" blades are usually anywhere from $45 to $60 to replace if one can find them.
