MyFishFinder.com Just like iceshanty but warmer
Send the blades to Fish307.com for exchange/resharpening http://www.fish307.com/augerbladeexchange.aspx
If you are that worried about the blades then I would prob get a new set. They(fish307) will takes yours and fix them giving you a set somedody else turned in. Or you could just buy a new set. What I did was got mine replaced with a used set and got a new set and kept them in the box just in case. For $30 for the new blades and $12 for the replacement used ones I figure thats pretty cheap insurance
The problem that I had is that the original blades on the auger were 8 inch Mora blades and they were junk right out of the box. My grandfather has had a 6 inch fine bore for three years now with no problems. I have even used it and it worked great! I was discussing with him and think the problem might be that the 8 inch just isn't good at cutting ice. If my trial with hand sharpening the blades doesn't work (the blades are sharp as hell now, cause I sliced a finger open by accident)- I am going to sell it. Might try a 6 inch Eskimo Barracuda curved blade auger beacuse my old Eskimo with straight blades works better than my fin bore.
Not trying to hijack this thread but maybe some of you Fin-Bore experts can help me with my handle problem:http://www.iceshanty.com/ice_fishing/index.php?topic=237221.0
