Can a Santoku Cut Fish?
Sep 27, 2026
Yes. A santoku can handle ordinary fish preparation very well. It is suitable for portioning boneless fillets, cutting fish for cooking and many general home tasks.
Boneless fillets
A sharp santoku can portion salmon, white fish and other fillets cleanly. Its broad blade gives good control on the board.
Skin and trimming
Small trimming jobs are possible, although a narrower petty or specialist fish knife can offer more precision in tight areas.
Whole fish
A santoku is not designed for repeatedly working through fish heads, backbones or heavy bones. Traditional whole-fish breakdown can benefit from a more substantial purpose-built knife.
Sashimi
A santoku can cut slices of boneless fish, but long sashimi cuts are easier with a long slicer because the cut can be completed in one smooth draw.
What should you avoid?
Do not twist a thin edge against bones or use the blade as a lever. Keep the cutting board suitable and the edge sharp.
Is it enough for home cooking?
For cooks who buy fillets rather than whole fish, a santoku is often all that is needed for routine fish preparation.
