| Option | Blade | Best for | Downside |
|---|---|---|---|
| Yanagiba (sashimi knife) | 210-270 mm single-bevel willow blade | Saku blocks sliced at home, weekly | One job; left-handed versions cost extra |
| Stainless yanagiba | Same shape, rust-resistant steel | Home kitchens without wipe-dry discipline | Purists say carbon takes a keener edge |
| Santoku substitute | Short double-bevel all-rounder | Occasional sashimi, cut in a few strokes | Sawing dulls the cut face |
| Supermarket pre-sliced | No knife at all | Sashimi as a sometimes-treat | Pay per slice; no thickness control |
