Bread knife WASABI BLACK 23 cm, KAI

Product detailed description

The KAI WASABI BLACK knife range does not try to turn every user into a master bladesmith, a Zen monk, or a collector. It comes from an environment where knives are used heavily and for long periods, so it focuses on uncomplicated daily use. In other words: less relationship therapy with your equipment, more normal work in the kitchen.

Main advantages:

• KAI WASABI BLACK is a Japanese utility range without unnecessary frills – it builds on durability, easy maintenance, and everyday usability, backed by more than a century of KAI experience in blade manufacturing.
• KAI was founded in 1908 in Seki, Japan, a city with a long knife-making tradition, and working with blades remains one of the main pillars of the entire brand to this day.
• The WASABI BLACK range is inspired by Japanese commercial kitchens and focuses mainly on robust construction, simple maintenance, and reliable everyday performance.
• The 6723B bread knife with a 23cm blade is designed for baked goods with a firmer crust and soft interior that you want to slice without unnecessary squashing.
• The special serrated edge of KAI easily bites into the crispy crust of bread, baguettes, or other baked goods, helping to guide the cut smoothly without significant pressure.
• The long 23cm blade gives you plenty of working space even for larger loaves, so you can cut a whole slice in a few natural strokes instead of short sawing motions.
• The serrated profile is also suitable for other foods with a firmer surface and softer structure inside, where a smooth edge might not be as practical.
• The polished blade is made of corrosion-resistant 6A/1K6 steel with a hardness of 58 ±1 HRC, which offers a reasonable balance between sharpness, durability, and low maintenance.
• The slightly curved spine of the blade provides a more secure support when holding and makes guiding the long knife more pleasant during regular slicing of baked goods.
• The matte black handle made of PP plastic is water-resistant and, thanks to the addition of bamboo powder, feels more natural in the hand than regular smooth plastic.
• The handle is seamlessly joined to the blade without any gaps where dirt could accumulate, making regular hygiene and maintenance easier.
• The handle length of 12.5 cm gives the long blade sufficient space for a secure grip and comfortable guidance when slicing larger loaves as well as smaller baked goods.
• The weight of 144 g keeps the knife pleasantly manageable, so it does not feel cumbersome even during prolonged slicing and responds well to hand movement.
• The simple black-and-silver design corresponds to the utility character of the entire WASABI BLACK range and prioritises function over effects that add nothing to the actual slicing.
• WASABI BLACK is one of KAI's industrially manufactured ranges, where the emphasis is placed mainly on functionality, durability, and ease of use instead of premium decorative materials.
• KAI does not treat blades as just another item in a catalogue – for more than a century, it has been developing know-how around cutting edges across kitchen, industrial, and other specialised blades.

Caring for your KAI WASABI BLACK knife:

• Wash the knife by hand in warm water with a mild detergent and dry it immediately after washing.
• Do not put it in the dishwasher, as high temperatures and harsh detergents can shorten the lifespan of the blade.
• Ideally, cut on a wooden or plastic chopping board. Glass, stone, ceramics and metal dull the blade faster.
• Do not use the knife on bones, frozen food, or for prying or other stress for which it is not intended.
• After cutting acidic or salty foods, rinse and dry the knife as soon as possible.
• To restore sharpness, it is best to use a water sharpening stone suitable for Japanese knives.
• Store the knife so that the edge does not touch other metal objects – for example, in a block, on a magnetic strip or with a protective blade cover.
• The polypropylene handle with bamboo powder does not require oiling or any other special maintenance.
