TL;DR: Usuba is a single-bevel vegetable specialist for precision cutting; Santoku is a versatile double-bevel knife for slicing, dicing, and mincing. Professional chefs handling delicate vegetable work prefer Usuba; home cooks seeking an all-purpose blade choose Santoku. Your cooking style and skill level determine the best match.
Did you know? The Santoku was created in Japan in the 1940s as a post-war, all-purpose kitchen knife combining earlier specialty blades (Source: Santoku — Wikipedia, 2025)
Many home cooks think all Japanese knives can handle the same jobs, but that’s not true. This mistake often causes problems when cutting vegetables or slicing meat. The Usuba and Santoku are made for different tasks, each with unique strengths. At KasumiJapan, we guide you in choosing the right knife based on your kitchen needs, cooking habits, and skill growth.
1. Definition and Characteristics of Usuba Knives
Usuba (薄刃) translates to "thin blade" in Japanese, reflecting its primary design purpose. These knives feature distinctive characteristics that set them apart from other Japanese blades.

Key Features:
- Single-bevel edge: Ground on one side only, creating an asymmetrical cutting angle
- Rectangular blade shape: Straight, thin profile measuring 6-9 inches in length
- Flat cutting edge: No curve, enabling precise straight cuts
- Cultural significance: Traditional tool for Japanese vegetable preparation (yasai)
Usuba knives excel at katsuramuki technique—creating paper-thin vegetable sheets for garnishes and sushi preparation. Master sushi chefs use Usuba for precise radish peeling and turnip cutting. The single bevel creates clean cuts without crushing delicate cell structures.
Professional usuba use a chisel grind with a hollow-ground back (urasuki); this geometry enables ultra-thin vegetable cuts but demands careful technique and maintenance.
2. Definition and Characteristics of Santoku Knives
Santoku (三徳) means "three virtues," referring to its ability to handle meat, fish, and vegetables with equal skill. This versatile knife represents modern Japanese cutlery evolution.

Key Features:
- Double-bevel edge: Sharpened on both sides for balanced cutting
- Sheep's foot blade shape: Curved spine with flat cutting edge
- Medium length: Usually 5-7 inches, perfect for home kitchens
- Granton edge option: Some models feature hollow dimples to reduce sticking
Santoku knives serve as excellent chef's knife alternatives for home cooks. Their compact size provides better control than longer Western blades. The flat edge promotes straight chopping motions, while the curved tip handles detailed work.
These knives work equally well for dicing onions, slicing chicken breast, and mincing herbs. Professional and amateur chefs appreciate the balanced weight distribution and comfortable grip.
Modern Santoku designs incorporate high-quality steels like VG-10 and SG2, offering superior edge retention and corrosion resistance.
Quick fact: Lab studies show steels tempered above ~60 HRC typically retain edges longer than mid-50s steels in controlled cutting tests. (Source: A Comprehensive Understanding of Knife Cutting — PubMed Central, 2023)

Blade Design Differences
The single-bevel Usuba creates incredibly precise cuts by focusing pressure on one edge. This design produces clean vegetable cuts without bruising. However, it requires right or left-handed specific models.
Santoku's double-bevel design offers balanced cutting performance. It handles various ingredients without needing specialized techniques. The symmetrical edge works naturally for both hands.
Cutting Performance

Usuba excels at paper-thin vegetable slicing, julienne cuts, and decorative garnish work. Its thin profile glides through delicate produce without tearing. Professional sushi chefs rely on Usuba for daikon radish sheets and cucumber ribbons.
Santoku provides versatile performance across multiple food types. It dices onions efficiently, portions fish fillets cleanly, and minces herbs finely. This makes it ideal for daily cooking tasks.
Learning Curve and Usage
Usuba demands advanced knife skills and proper technique training. New users often struggle with the single-bevel cutting angle. Mastering Usuba requires practice and possibly professional instruction.
4. Maintenance and Care: Usuba and Santoku Knives
Proper maintenance preserves knife performance and extends blade life. Each knife type requires specific care approaches.

Usuba Maintenance:
- Sharpening: Use whetstones exclusively, maintain single-bevel geometry (uraoshi flat)
- Storage: Magnetic strips or knife blocks with proper blade protection
- Cleaning: Hand wash immediately, dry thoroughly to prevent rust
Santoku Maintenance:
- Sharpening: Whetstones or quality sharpening systems (8–10 degrees per side)
- Honing: Light honing rod maintenance between sharpenings
- Care: Standard knife care practices apply

Universal Best Practices:

Store knives properly to prevent edge damage. Magnetic strips work well for daily-use knives. Knife blocks protect blades but require clean, dry storage.
