Mitsumoto Sakari Japanese Kiritsuke Chef Knife (7 Inch, Micarta Handle, Sandalwood Box)

What makes HAP40 powder steel superior to regular knife steel?

HAP40 powder steel originates from aerospace manufacturing and achieves 67 HRC hardness compared to 55-60 HRC in standard knives. The powder metallurgy process creates fine, evenly distributed crystals that maintain sharpness significantly longer. Higher cobalt content provides better rust resistance whilst the uniform grain structure delivers consistent cutting performance across the entire blade edge.

How long does the hand forging process take for each knife?

Each knife requires 45 days of traditional Japanese hand forging by skilled artisans. This extensive process involves multiple heating, hammering and cooling cycles to achieve the distinctive Damascus pattern and optimal blade geometry. The time-intensive approach ensures superior grain structure and creates the characteristic hammered texture that enhances both performance and aesthetics.

What cutting tasks is the kiritsuke design best suited for?

The kiritsuke design excels at cutting fish, vegetables, seafood and meat with equal precision. The slightly curved spine reduces food contact surface area, improving cutting efficiency and preventing ingredients from sticking. The 7-inch blade length provides excellent control for detailed trimming work whilst being versatile enough for general food preparation tasks.

Why is the Micarta handle material better than wood or plastic?

Micarta offers superior properties compared to traditional handle materials. Originally developed for electrical insulation, it's completely waterproof and won't absorb odours or bacteria. The material is lighter than wood, reducing hand fatigue during extended use. The non-slip surface pattern provides secure grip even when wet, making it ideal for professional kitchen environments.

How should I maintain the HAP40 steel blade to prevent rust?

HAP40 steel requires proper care despite its rust resistance. Rinse the blade immediately after use and dry thoroughly with a clean cloth. Avoid cutting acidic foods for extended periods and never leave the knife wet. The blade can be sterilised in boiling water for sushi preparation. Store in a dry environment and avoid contact with corrosive substances.

Can this knife cut through bones or frozen foods?

No, this knife should not be used on bones, frozen foods or other hard materials. The 67 HRC hardness makes the blade extremely sharp but also more brittle than softer steels. Using it on inappropriate materials can chip or damage the edge. Stick to cutting fish, vegetables, meat and other soft to medium-firm ingredients for optimal performance and longevity.

What's included in the sandalwood presentation box?

The complete package includes the kiritsuke knife, premium sandalwood gift box, knife cleaning cloth, maintenance instructions and user manual. The sandalwood box provides elegant presentation and safe storage. The cleaning cloth is specifically designed for blade maintenance whilst the instructions cover proper use, care and sharpening techniques.

How does the 15-degree edge angle compare to Western knives?

The 15-degree edge angle is significantly sharper than typical Western knives which usually feature 20-25 degree angles. This acute angle requires less force to cut through ingredients and provides cleaner cuts with minimal cellular damage. However, the sharper angle requires more careful handling and proper maintenance to preserve the edge geometry and cutting performance.
