Japanese Knife Types: A Complete Visual Guide
Japanese knives are among the most specialized in the culinary world — with distinct blade shapes designed for specific tasks. Understanding the different types helps you choose the right knife for your cooking style.
Overview: Japanese Knife Categories
Japanese knives fall into two main categories based on their bevel (edge grind):
- Ryoba (両刃) — Double-bevel: Sharpened on both sides. User-friendly, suitable for all skill levels.
- Kataba (片刃) — Single-bevel: Sharpened on one side only. Professional tools requiring skill.

Which Knife Should You Buy?
If you're buying your first Japanese knife:
→ Santoku (165mm) — the most versatile, beginner-friendly option
If you cook professionally or want a longer blade:
→ Gyuto (210mm) — the professional standard
If you want to add a second knife:
→ Petty (120-150mm) — for detail work that's awkward with a larger knife
If you cook lots of vegetables:
→ Nakiri (165mm) — the vegetable specialist
If you fillet fish regularly:

Recommended 3-knife set for home cooks:

Frequently Asked Questions
How many types of Japanese knives are there?
There are dozens of traditional Japanese knife types, but 5-7 are commonly used in modern kitchens: santoku, gyuto, nakiri, deba, yanagiba, petty, and usuba. Professional sushi chefs may use 10+ specialized knives.
What is the difference between single-bevel and double-bevel?
Double-bevel (ryoba) knives are sharpened on both sides — easier to use and maintain, suitable for all cooks. Single-bevel (kataba) knives are sharpened on one side only — offer superior precision but require skill to use and sharpen. Beginners should start with double-bevel.
What Japanese knife should a beginner buy first?
A santoku (165mm) for home cooks who primarily cook Japanese/Asian food, or a gyuto (210mm) for those who cook Western-style. Both are double-bevel, all-purpose knives that handle most kitchen tasks.
