If you are ever in Kenora I highly reccomend Meadows Sharpening Service.
He did the blades and the chisel point on my Jiffy 10" and it is way sharper than it was when it was new.
Set me back only $10 to boot. Awesome guy.
Don't get the blades sharpened without taking the whole auger in to get the chisel point dressed or you are wasting your time. That was what Mr. Meadows above told me. From the way it cuts now I believe him.
Kind of peed me off having to drive all the way home to get my auger but the results were most excellent.
Hope this is of some use to you.
Regards,
Glen
