The yanagiba is the iconic single-bevel sashimi knife of Japanese cuisine. When buying, the most-debated question is length: 240mm or 270mm?
This guide draws on Japanese sushi chef interviews, restaurant equipment surveys, and home sashimi prep advice to give you a clear answer.
TL;DR
| Use Case | Length |
|---|---|
| Home sushi prep (1-2 portions) | 240mm |
| Small fish (sardines, mackerel) | 240mm |
| Medium-large fish (yellowfin, sea bream) | 270mm |
| Professional sushi restaurant | 270-300mm |
| First yanagiba purchase | 240mm (recommended) |
Why Length Matters for Yanagiba
Unlike gyuto/santoku, the yanagiba is designed for one motion: a single, smooth pull-cut for sashimi. This single-stroke design has a critical constraint:
The blade must be longer than the fish piece you’re slicing.
A 200mm yanagiba can’t cleanly slice a 250mm tuna loin. The pull stroke requires the entire fish piece to clear the blade in one motion—any sawing destroys the sashimi’s texture.
Standard fish sizes vs yanagiba lengths
| Fish/Cut Size | Recommended Yanagiba |
|---|---|
| Sardines, mackerel (~150mm) | 240mm sufficient |
| Salmon side (~250mm) | 240mm tight, 270mm comfortable |
| Yellowfin tuna section (~300mm) | 270mm required |
| Large tuna loin (~400mm+) | 300mm professional |
Detailed Comparison: 240mm vs 270mm
| Aspect | 240mm | 270mm |
|---|---|---|
| Total length | ~390mm | ~420mm |
| Weight | ~145g | ~165g |
| Best fish size | Up to 250mm cuts | Up to 300mm cuts |
| Storage | Standard knife block | Often requires special storage |
| Cutting board needed | 400mm+ | 450mm+ |
| Counter space | Standard kitchen | Larger kitchen |
| Skill needed | Medium | Higher |
| Forgiveness | More forgiving | Less forgiving |
| Resale value | Higher (more buyers) | Lower (specialty) |
| Price (entry) | $100-200 | $130-250 |
| Price (premium) | $400-800 | $500-1000 |
When to Choose 240mm
Home cook, occasional sashimi
You prep sashimi 1-4 times per month, work with sardines/salmon/small tuna pieces. 240mm gives you enough length without overkill.
Smaller kitchen / cutting board
If your cutting board is under 450mm long, a 270mm yanagiba requires constant repositioning. 240mm fits standard cutting boards.
First yanagiba
Japanese sushi instructors universally recommend starting with 240mm. Once you’re comfortable, you can graduate to 270mm if needed.

What Japanese Sushi Chefs Actually Use
Entry-level apprentice (修業初年度)
Often given a 240mm yanagiba as their first knife. Used for everyday sashimi prep on smaller fish.
Mid-level chef (中堅)
Carries both 240mm and 270mm for different applications. 240mm for daily small-piece work, 270mm for service.
Sushi master (大将)
Typically uses 270mm primary, 300mm for tuna. May own a custom honyaki 270mm as their signature knife.
“240で始めて、3年経ったら270を買い足す。これがプロの基本パターン” — translated from Japanese sushi forum: “Start with 240, after 3 years add a 270. That’s the pro pattern.”
Beyond Length: Other Yanagiba Considerations
Steel type
- Shirogami (white steel): Sharpest, requires immediate drying
- Aogami (blue steel): Sharp + slightly tougher
- Inox (stainless): Easier maintenance, slightly less sharp
- Powder steel (R2/SG2): Modern premium, easy maintenance
Handle (Wa-handle)
- Magnolia wood + buffalo horn (standard)
- Ho wood + plastic (entry level)
- Ebony or rosewood (premium)
Geometry
- Sakai-style: Traditional, hand-forged
- Modern-style: Machine-forged, more uniform
Common Mistakes
Mistake 1: Buying 300mm as a first yanagiba
Tempting because “bigger is more pro.” Reality: a 300mm yanagiba is hard to maneuver, requires huge cutting boards, and overwhelms most home kitchens.
Mistake 2: Using yanagiba for non-sushi tasks
Yanagiba is single-bevel and specialized for one cut motion. Don’t use it for chopping vegetables (chips the edge) or as a general-purpose knife.
Mistake 3: Not getting proper sharpening
Single-bevel knives sharpen differently than double-bevel. Don’t take it to a regular knife sharpener. Either learn yourself or send to a Japanese-specialty sharpener.
Conclusion
For 80% of home sashimi enthusiasts: 240mm yanagiba.
It’s the right length for typical home kitchens, fits common cutting boards, and matches the fish sizes you’re likely to work with.
Choose 270mm only if you:
– Regularly buy large tuna/salmon pieces
– Have a large kitchen
– Plan to upgrade after using a 240mm
Recommended first yanagiba: Yoshihiro Inox 240mm ($150) — easy maintenance stainless, sufficient sharpness, beginner-friendly.
