Eze Lap hook sharpener.
Some to a lot of the lures I buy, comes with not the sharpest of hooks. Often, I have to touch them up. There are some hooks that have dull barbs and I carefully touch them up as well.
Sometimes I pick up lures on the ground or fish them from a snag and then I touch up them hooks and use those lures. Yeah, I am a cheapo, but sometimes I find a lure and wonder if it was a hot lure.
