Step-by-Step Guide to Fix a Chipped Blade
Can often be fixed at home. You need the right tools and some care. Here’s how to fix small chips and get your knife sharp again.
Step 1: Whetstone preparation
First, locate the care guide for your whetstone. Some stones need to be wetted before use; others need to stay dry. If your stone requires soaking, soak it in water for 10 to 15 mins or follow its guide.
Put the stone on a damp towel. Make sure it doesn’t move while you work.
Step 2: Mark the Chip
Mark the chipped portion of the blade with a marker. So you can see where to take the metal off as you sharpen.
Step 3: Take Out The Chip
Use a rough 400-grit stone to start. Use it to grind away the chipped part. Keep the blade at the angle that suits its edge. A single-bevel or double-bevel knife may need a different angle. Move the blade over the stone with slow, even strokes. Use light pressure. Work with care until the chip is gone and the edge is smooth.
Note: Large chips need a lot of metal removal. If the chip is deep, take the knife to a skilled knife sharpener.
Step 4: Keep the Blade Shape
Do not grind only the chipped spot. This can change the blade. Work along the full edge as needed. Check the shape often as you go.
Step 5: Sharpen the Edge
Once the chip is out, use a finer stone, 1,000 or 3,000 grit. Stick to the care guide for the stone and keep your knife at the right angle. Go over the edge to refine it smoothly. Then dry and clean the blade. A leather strop may help remove small burrs left by sharpening.
Test the New Edge
Can test the edge with a sheet of printer paper. Hold the paper away from your body and keep your fingers clear of the blade.
Try to cut the paper with a slow, light stroke. If the knife cuts cleanly without snagging, the edge may be ready to use. Do not test it on your fingers.
How to Stop and Fix a Chipped Blade in the Future
A few simple habits can help protect your knife.
- Use a wooden or plastic cutting board. Hard surfaces can harm the edge. Instead, use a plastic or wood cutting board.
- Use the right knife: Never cut bone with a knife. When the job calls for it, use a heavy meat cleaver.
