With our Flexible Hook Sharpener you will never have an excuse for blunt hooks again. Small in size and therefore easy to carry. Put the hook point in the Flexible Hook Sharpener and move it up and down a few times. The sand crystals in the block will make the hook razor sharp again. Hooks with coating will lose their coating, but that does not matter. You can also use the Flexible Hook Sharpener to file along the hook to make it sharp and remove burrs.
