Hook Sharpener 4” Diamond Stone

Simple design with one groove on one side and two grooves on the other side. 

1. Grip Securely: Hold the hook firmly with your thumb and forefinger, or use pliers for larger hooks.
2. Find the Angle: Position the file at a low, consistent angle (around 10-15 degrees) to the hook point, matching the natural bevel.
3. Stroke Towards the Point: Draw the file across one side of the hook point, moving away from you and towards the point (or pulling the hook downalong the file).
4. Work All Sides:
   • File the top edge of the point a few times.
   • Rotate the hook and file the opposite side.
   • File the underside of the point.
   • Use a final stroke straight across the top to remove any burrs.
5. Use Light Pressure: Apply just enough pressure for the file to bite; too much pressure can damage the hook.
6. Test for Sharpness (Nail Test): Lightly drag the point across your thumbnail. If it sticks and catches, it's sharp. If it slides, continue filing.
7. Minimal Strokes: Use only a few strokes (5-7 per side is common) to avoid thinning the hook too much.
