I purchased this to hang on my fly vest and sharpen my fly hooks. This is a crude sharpener,,,will get the job done with time. When I fish, I don't wish to take a lot of time. I have had sharpeners in the past that did the trick. This one doesn't. Again, it will get the job done, but I wouldn't recommend this to a friend. Spend a little more money buying, and a lot less time sharpening when you are on the water. Two stars is listed as fair, one star is poor....I would call this 'below average' rather than fair.
