With Rozemeijer’s Flexible Hook Sharpener, you’ll never have an excuse for blunt hooks again. Small and therefore easy to carry around. Put the hook point in the Flexible Hook Sharpener and move it up and down several times. The sand crystals in the block will make the hook razor sharp again. Coated hooks will lose their coating, but that doesn’t matter. Also, you can file along the hook with the Flexible Hook Sharpener to sharpen the hook and remove burrs.
