How to check and sharpen a hook point
Test a hook against your thumbnail, revive a blunt point with a file, and retire hooks that have had too much.

What this skill is for
A blunt hook is the most common reason a hooked fish gets away and the least obvious thing a angler checks. A sharp point needs almost no force to penetrate; a skatey one needs a strike hard enough to break light tackle.
What you need
- A hook file or a small ceramic sharpener
- Your thumbnail
- A waste tin for retired hooks
Step by step
- 01
Test it on a thumbnail
Draw the point lightly across your thumbnail. A sharp hook digs in and stops. A blunt one skates across the surface. Do this after every snag, every hard fight and every trip to a rocky bottom.
- 02
File a few strokes
With a small hook file or ceramic sharpener, take two or three light strokes along the point, keeping the original angle. Rinse off any metal dust before you use it.
- 03
Check the barb
The barb should be clean and sharp, or neatly squeezed down if you're releasing fish — a crushed, ragged barb damages tissue and makes unhooking harder.
- 04
Retire the tired hooks
A hook that has been sharpened repeatedly is thinner and weaker than it was. Any hook that's bent, corroded, or visibly thinner at the point goes in the waste tin.
- 05
Keep hooks dry and separated
Store them in a box with compartments, away from damp. Rust starts at the point, which is exactly where you can't afford it.
Where it goes wrong
- Fishing a hook that skates over the nail because it's the only one in the box.
- Over-filing a thin-wire hook into a needle that straightens on a big fish.
- Leaving a burr from filing, which stops the point penetrating cleanly.
- Reusing a rusted or bent hook because it still looks fine.
