I'm still searching for the "perfect" hook sharpener. I'm a big stickler about having extremely sharp hooks, and I'm almost never satisfied with hooks right out of the packaging. I used the orange colored, pencil shaped stone that Bass Pro carried for a couple years. But they wear out fast, and they stopped carrying them. Flat sharpening stones with a grooved cut-in have the same problem - they work great for a short time, then lose their bite. The battery operated ones are gimmicks in my opinion. Has anyone come up with a better solution?
