What Sujihiki Length Should You Choose? 240 vs 270 vs 300 mm
Sep 27, 2026
For most home kitchens, Sujihiki lengths around 240, 270 and 300 mm cover the main choices. The best size depends on your board, storage and the largest proteins you regularly slice.
240 vs 270 vs 300 mm at a glance
| Length | Best fit | Main trade-off |
|---|---|---|
| 240 mm | Compact kitchens, moderate roasts, poultry, fish fillets | Less reach on very large pieces |
| 270 mm | Balanced all-round slicing | Needs more board and storage space |
| 300 mm | Large roasts, long fish fillets, maximum draw length | More demanding to store and maneuver |
When does 240 mm make sense?
When board space is limited or your usual food is not especially large. It still offers noticeably more reach than many chef’s knives.
Why choose 270 mm?
It is a useful middle ground for cooks who regularly slice larger proteins but do not need the full footprint of 300 mm.
When is 300 mm useful?
When you often slice large roasts or long fish fillets and want to finish the cut in one uninterrupted stroke.
Is longer always better?
No. Extra length is only useful if you have the board space, storage and control to use it comfortably.
How should a home cook decide?
Measure your board and think about the largest food you slice repeatedly. If 240 mm already spans the job comfortably, extra length may add little. If you often run out of blade, 270 or 300 mm becomes more useful.
Do not forget the handle
Total knife length matters for storage and maneuverability, so consider handle size as well as edge length.
