KAI Wasabi Black – Chef's Knife 20 cm (cod. 6720C)

The KAI Wasabi Black 20 cm chef's knife (cod. 6720C) is a Japanese professional kitchen tool with 6A/IK6 stainless steel blade, hardness 58 (±1) HRC and ergonomic grip in black polypropylene with bamboo powder. Weighing 149 g, it offers precise balance and meets the daily needs of chefs, restaurant brigades, hotels and catering operations seeking consistent reliability at a competitive price.

Blade: 6A/IK6 stainless steel, 58 HRC

The 20 cm blade is made of 6A/IK6 stainless steel of the latest generation, with heat treatment bringing hardness to 58 (±1) HRC. This hardness level ensures long-lasting sharpness and precise cuts on meat, fish and vegetables, reducing the frequency of in-service resharpening. The slightly arched back facilitates the rocking motion on the cutting board, a fundamental technique in professional food preparation.

Ergonomic handle in PP with bamboo powder

The black polypropylene (PP) handle with bamboo powder measures 12.5 cm and features an oval section that ensures a secure grip even in wet environments or with oily hands. Resistant to water and chemical agents, it maintains its characteristics 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 the Wasabi Black 20 cm

• Slicing meat, fish and vegetables with precision
• Carving and mincing ingredients in rapid preparations
• Cutting board work for aromatics and fresh herbs
• Sushi, sashimi and Japanese fusion cuisine preparations
• Daily service in restaurant, hotel and catering kitchens

Maintenance and blade 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-grit sharpening stones or professional systems dedicated to Japanese knives. Due to the blade's elevated hardness (58 HRC), avoid traditional steels that could chip the edge.

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