I like the chemically sharpened hooks, but they do get dull and I seem to always make them duller trying to sharpen them. I've been sharpening hooks since 1959, so it isn't a lack of skill. I can see the dark steel under the silver coating after sharpening them, so I'm actually removing the chemical layer. Those begin to rust in the altered areas quicker than regular hooks. So, when a chemically sharpened hook stops grabbing a fingernail I now replace it.
I have a set of Akransas Stones made of novaculite, a glassy silica rock (similar to quartz) that comes cut in various grits, all requiring light oil to keep the pores from clogging with metal. Occasionally I steam clean them. Those stones can turn a cheap hunting knife blade into one you can shave with. I buy them locally near where they are made, but they are online at Click Here
I have an old collectible flat one about 4" long, 1/4" wide and 1/8" thick for treble hooks. I see they still make the hook sharpener stone, but mine is for round pointed hooks, not faceted points. When I sharpen I always make the point slice against the stone gently, keeping a high angle. Don't hold the hook shank close to the stone. You only want to restore the tip of the point. Make a pass or two then test by pushing the point against a fingernail. Keep sharpening until the hook grabs easily.
I switched to premium hooks a while but realized they dull about as fast as cheap hooks due to our rocky bottoms. There are several popular lower priced brands that are plenty sharp out of the package, ready to use, and easy to resharpen. I realize there's a hook on the market now that can supposedly split an atom, but all you need is a hook that will penetrate the roof of a bass mouth. An aggressive hookset with properly matched quality line and rod working a truly sharp hook designed for your lure will help boat your share of fish. I wouldn't advise anyone changing all the hooks to better. I started to do that years ago but can't fish them all before the hooks rust. Change to better hooks the day you select a new player lure. Carry a modest supply of types and sizes, kept in a plastic container with some dry white rice or commercial desiccant.
