Blade: 6A/IK6 Stainless Steel, 58 HRC

The 20 cm blade is made from 6A/IK6 stainless steel of latest generation, with heat treatment bringing hardness to 58 (±1) HRC. This level of hardness guarantees lasting sharpness and precision cuts on meat, fish and vegetables, reducing the frequency of re-sharpening during service. The slightly curved spine facilitates the rocking motion on the chopping board, a fundamental technique in professional preparation.

Ergonomic Handle in PP with Bamboo Powder

The polypropylene (PP) handle in black with bamboo powder measures 12.5 cm and features an oval section that ensures a stable grip even in wet environments or with oiled hands. Resistant to water and chemical agents, it maintains its properties over time even with intensive use in professional kitchens. The overall weight of 149 g helps reduce fatigue during long working sessions.

Professional Uses of Wasabi Black 20 cm

• Slicing meat, fish and vegetables with precision
• Trimming and mincing ingredients in rapid preparations

• Sushi, sashimi and Japanese fusion cuisine preparation
• Daily service in restaurant, hotel and catering kitchens

Blade Maintenance and Care

Cleaning: wash by hand with neutral detergent after each use and dry immediately with a soft cloth. Do not wash in the dishwasher: prolonged exposure to hot water and aggressive detergents compromises sharpness and can damage the handle.

Sharpening: use progressive-grain sharpening stones or professional systems dedicated to Japanese knives. Due to the high hardness of the blade (58 HRC), avoid traditional sharpening steels which could chip the edge.

Storage: keep in knife block, magnetic bar or drawer with blade guard to protect the edge between uses.
