The Japanese paring knife is an essential versatile tool in the kitchen. Thanks to its short and precise blade, it excels at peeling, slicing, or dicing vegetables and fruits. But to remain efficient, it must be maintained carefully.
Sharpening is a key step to maintaining the precision of a Japanese paring knife, whose hard and thin steel requires a specific approach.

Why sharpen a Japanese paring knife regularly?
A demanding edge
The Japanese paring knife is often forged in hard steels (VG10, Damascus steel, carbon). This steel retains its edge for a long time but requires precise sharpening to avoid damage.
Risks of a dull knife
A dull paring knife can:
Slip on food and increase the risk of cuts,
Crush fruits and vegetables instead of cutting them cleanly,
Lose its role as an essential precision knife in the kitchen.
What tools to use to sharpen a Japanese paring knife?
Japanese water stones
They are essential for respectful sharpening:
Grit 1000: recreates the blade edge,
Grit 3000: refines and homogenizes,
Grit 6000-8000 : polite and gives a razor-sharp cut.
Recommended Angle
A Japanese paring knife is sharpened at 12°-15°. This precise angle allows for clean cuts without weakening the blade.

Step-by-step Tutorial: Sharpening a Japanese Paring Knife
1. Preparation
Soak the whetstone for 10 to 15 minutes,
Place the stone on a stable support,
Clean the blade and slightly moisten it.
2. Sharpening
Position the blade at 12°-15° on the stone,
Slide in regular strokes from base to tip,
Work first with 1000 grit, then 3000, then 6000+,
Alternate sides to maintain the edge balance.
3. Finishing and Testing
Pass the blade over leather to eliminate the burr,
Test on a tomato or paper sheet: the cut should be smooth and precise.
Common Mistakes to Avoid
Using a Western steel honing rod, too aggressive,
Changing the angle during sharpening,
Sharpening too quickly or with excessive pressure,
Forgetting to properly soak the stone.
Maintenance of the Paring Knife After Sharpening
Dry the blade carefully,
Store the knife in a sheath or magnetic block,
Prefer softwood or bamboo cutting boards,
Avoid prolonged moisture, especially for carbon steels.
What is the difference between a Japanese and Western paring knife when sharpening?
The Japanese paring knife is sharpened at a finer angle (12°-15°) than its Western counterpart (20°-22°). Its harder steel allows for a more durable edge but is also more sensitive to sharpening errors.
Can a Japanese paring knife be sharpened with a manual sharpener?
Some fixed-angle manual sharpeners can be suitable, but whetstones offer a much more precise result and are more respectful of the blade.
What is the ideal sharpening frequency for a Japanese paring knife?
With daily use, a complete sharpening every 2 to 3 months is recommended. Between sharpenings, a quick pass on a ceramic honing rod or leather is enough to maintain the edge.
How long does a sharpening session last?
Depending on the state of the blade, a complete sharpening of a Japanese paring knife takes on average 15 to 30 minutes.
What are the signs of poor sharpening?
Irregular blade or visible micro-teeth,
Edge catching on food,
Loss of precision on fine cuts.
What type of stone is recommended for a first purchase?
A combined 1000/6000 stone is ideal for beginners: the 1000 grit restores, the 6000 grit polishes and ensures a razor-sharp finish.
Does a Japanese paring knife made of carbon steel require special care?
Yes. After sharpening and washing, it must be dried immediately and then lightly oiled (camellia or sunflower oil) to prevent oxidation.
