If it's a crankbait I would not bother sharpening or recoating the hooks if it's a factory hook. All but the top of the line makers use lower quality hooks to keep their prices down and/or to increase their profit margins. I replace practically all my factory crankbait hooks with Gamakatsu extra wide gap short shank hooks before the bait ever gets wet. Gama's don't or rarely rust and they will stay sharp through almost anything. At most they would require only a mild touch up if you overthrow into the rocks, plow the bottom or set the hook on everything that "might" be a fish like I do. I also like to put a larger size hook in the rear than what came on it from the factory. That may mess with the baits action and dive depth a little but with the higher hook up rates that you will get with the larger hook I think you come out ahead in the long run. sw
