Putting an edge on the blade, never the corkscrew
- Fold the corkscrew away and open only the 10.5 cm blade, so the worm cannot catch your fingers on the stone.
- Wrap the creamy handle in a cloth or wear a thin glove: stone slurry and metal dust grey a pale handle quickly.
- On a combination whetstone, around 1000 grit and then 3000, hold the blade at roughly 20 degrees and sweep from heel to tip, matching the strokes on both sides.
- Remove the burr with a few light passes on leather or folded newspaper.
- Wipe the blade and the inox bolster clean before folding.
The worm never needs sharpening; its point only has to stay straight. Done this way, a light-coloured wooden handle folding knife keeps both its edge and its pale finish.
