I actually question sharpening hooks for fishing.
If a brand of hook is not sharp enough, don't use them!
If you sharpen a hook, then you are actually increasing the chance of the extra sharpened hook cutting or pulling its way free, potentially increasing hookpulls.
Add to that, obviously you know that you the finer the point the more chance of it being blunted, or bending over.
I don't think that my hooks need sharpening, I use them straight out the packet.
A few years ago now, I put a hook on a rig, and cast it out. That hook caught me a 26lb mirror. I then took that same rig back to a local water, where it was used again, and landed a load more fish until I eventually lost or blunted it.
In between fish it was rebaited, recast no sharpening.
Since then I have landed hundreds of fish from a variety of waters on hooks straight out of the packet.
As an aside for you, ask yourself, you know some tackle is sold to make money for tackle manufacturers, there is no need for it; how much do I really need to sharpen hooks so going out and buying a hook sharpening kit...
