A large screw (preferably steel and with a pronounced thread)
A dull knife
A cloth or glove to hold the screw firmly
Step-by-step guide to sharpening a knife with a screw
1. Clean the screw:
Make sure it is clean and free of rust to avoid contaminating the knife blade.
2. Hold the screw firmly:
You can secure it in a vise or simply hold it with a sturdy glove to protect your hand.
3. Sharpen the knife:
Slide the knife’s cutting edge along the screw’s thread, mimicking the motion you would use with a sharpening steel. Do this at about a 20-degree angle, alternating between both sides of the edge about 5-10 times.
