Just picked up my ION 8" auger. Looks like a pretty well made machine but I noticed the blades seemed pretty dull for a brand new auger. Is this normal for a power auger?? The blades I used all last season on my 7" Mora hand auger are a lot sharper than the blades on the new ION. I can't say how it cuts because there is nothing to cut yet. I would assume though that an electric auger needs very sharp blades to get the job done before the battery discharges. Any thoughts on the subject? Thanks
