Pros: One point in defense of the sharpener and the reason I rated it two instead of one (I would have rated it 1.5 if I had that option) is this: the job did get done, but with many strokes.
Cons: I was very disappointed when this ice auger blade sharpener arrived. I did not expect the accompanying instructions to inform me that this product will only be a temporary fix to a dull blade and that I should replace the blades with new ones. I also expected sturdier construction. The instructions did not inform me that, when using it, I should be very conscientious in holding the sharpener at an exact angle to avoid forming a burr. The instructions said that 12 strokes should do the job. Actually 12 strokes did not begin to sharpen the blade. I started to notice a positive change at about 60 strokes.
