Ever tried to cut a tomato with a dull knife? It squishes instead of slices. This gets even worse with dull ceramic blades. Unlike metal knives, ceramic needs special care to stay sharp. Let’s see how to keep your ceramic blades razor-sharp.
Why Ceramic Knives Need Special Care
Ceramic knives stay sharp much longer than metal ones. A good Kyocera ceramic knife keeps its edge up to 10 times longer than steel. But when they do get dull, you need special tools.
Why? Ceramic is harder than stainless steel but more brittle. Using regular tools on ceramic can:
- Break your knife
- Chip the blade
- Damage your sharpening tool
Best Tools for Ceramic Blades
1. Diamond Sharpening Stones
A diamond sharpening stone works best for ceramic blades. Diamond is harder than ceramic, so it can shape the edge well.
Good ones have:
- Fine grit (1000+)
- Flat surface
- Water base
Work Sharp makes good diamond stones just for ceramic knives.
2. Electric Sharpeners
Some electric sharpeners have a 3 stage process with one part made for ceramic. These make sharpening easy for home cooks.
Chef’sChoice sells models with diamond parts that work on ceramic. You don’t need special skills to use them.
3. Pro Sharpening Help
Many knife shops offer a sharpening service for ceramic knives. If you own costly kitchen knives like a Kyocera knife or fancy chef knife, this might be your best choice.
These pros use special diamond wheels to fix the edge. It costs $10-25 per knife, but makes them like new again.
4. Diamond Rods for Touch-ups
A diamond sharpening rod can fix slightly dull edges. These look like normal steel rods but have diamond dust on them.
Note: Regular steel rods for stainless steel will harm ceramic blades!
How to Sharpen Your Ceramic Knife
Getting a sharp knife edge on ceramic takes some care. Here’s how with a diamond stone:
- Set up your space
- Put a non-slip mat under your stone
- Add water if needed
- Keep a towel handy
- Find the right angle
- Most ceramic knives need a 15-20 degree angle
- Kyocera ceramic blades may need specific angles
- Use a guide if you’re not sure
- Use light touch
- Let the diamond do the work
- Press more gently than with steel knives
- Sweep the blade across the stone
- Work both sides the same
- Count your strokes on each side
- Keep the same angle all the way
- Test it
- Try cutting paper – a sharp knife cuts clean
- Look for any chips or rough spots
Tips for Kyocera Knives
Kyocera knife products are very popular ceramic blades. They offer their own sharpening service, which many owners like best.
If you sharpen at home:
- Use only diamond tools
- Follow their angle (often 16 degrees)
- Send badly damaged knives to them
Kyocera suggests pro sharpening every 1-2 years for normal home use.
When to Get Pro Help
Try a pro sharpening service when:
- Your blade has chips
- The edge is very dull
- You’re not sure about your skills
- You have costly kitchen knives worth the care
Many knife shops and cooking stores can help. Some Kyocera ceramic sellers offer this too.
Keep Edges Sharp Longer
Your ceramic chef knife will stay sharp longer if you:
- Use only wood or plastic cutting boards
- Never cut frozen food or bones
- Store with blade guards
- Wash by hand – no dishwasher
- Use the knife only for what it’s made for
