Chef Tanaka - 7-Piece Japanese Knife Set

Chef Tanaka 7-Piece Japanese Knife Set: Everyday technical versatility

The expert review at a glance:

• Material: 5CR15MoV martensitic stainless steel. A hardness of 53–54 HRC that prioritises toughness and impact resistance.

• Use: A complete 7-piece arsenal designed to cover every kitchen task, from the raw power of the boning knife to the finesse of the paring knife.

• Maintenance: Alloy optimised for easy sharpening.

Why choose 5CR15MoV steel for your kitchen?

Robustness, toughness and easy maintenance

In the world of cutlery, hardness isn't everything. The 5CR15MoV steel used in the Tanaka range is a martensitic steel chosen for its great resilience. With a rating of 53–54 HRC, this steel is less brittle than ultra-high carbon steels. In practice, this means your blade has superior "toughness": it absorbs impacts without chipping, making it the ideal partner for dynamic, daily cooking. It strikes the perfect balance between sufficient chromium content for corrosion resistance and carbon for effective sharpness.

Unlike steels like 10CR15 (Damascus) which require some mastery of water stones, 5CR15MoV stands out for its ease of maintenance. The edge of the Tanaka blade responds exceptionally well to a steel honing rod. A regular touch-up of just a few seconds before each cooking session is enough to realign the burr and keep cuts effortlessly smooth. A valuable time-saver for both professionals and passionate home cooks.

Chef Tanaka Set Line-up: 7 tools, 7 culinary functions

The core essentials: Chef's knife, Santoku and Nakiri

These three blades form the heart of your arsenal. They share an essential versatility but cater to distinct cutting techniques:

1. The Chef's Knife (200g): The ultimate multi-purpose tool. Its curved profile is optimised for a rocking motion. With 200g of balanced weight, it turns chopping herbs and portioning proteins into a smooth, effortless task.

2. The Santoku (191g): "Santoku" means "three virtues" (slicing, dicing, mincing). Shorter and more manoeuvrable than a chef's knife, it excels at precision slicing of vegetables and boneless proteins.

3. The Nakiri (217g): Recognisable by its rectangular shape, this is the vegetable specialist. Its flat blade makes full contact with the board right from the start of the cut. Its broad profile also lets you use it like a scoop to transfer chopped ingredients straight to the pan.

Precision work: Paring knife, Utility knife and Boning knife

For tasks requiring greater dexterity, these three knives offer pinpoint control:

• The Paring Knife (86g): Small and nimble, it is essential for peeling, trimming small fruit or coring vegetables with agility.

• The Utility Knife (100g): Between a paring knife and a chef's knife, it is the technical choice for intermediate cutting tasks, such as slicing hard cheeses or small dry sausages.

• The Boning Knife (150g): Its thin, rigid blade follows joints and bones closely to separate muscle tissue without waste. Note: it is designed to work around bones, not to chop through them.

Dedicated performance: The serrated bread knife

The Bread Knife (173g) completes this 7-piece set. Unlike straight blades, its serrated teeth break through the tough crusts without crushing the soft crumb. It is the essential tool for preserving the open crumb structure of artisan breads.

Design, Ergonomics and Craftsmanship

The Tanaka set comes with two types of handles, each chosen for its technical properties:

• Pakkawood (exclusive to the Forest Wood colour): a heat-compressed wood and resin composite. Rot-proof, it withstands moisture and temperature fluctuations while maintaining dimensional stability over time. Its finish showcases the natural wood grain beneath a protective resin coat.

• Epoxy resin (Ocean Blue, Tierra del Fuego, Ivory and Sumi Black colours): a synthetic material that delivers uniform colour depth, provides a non-slip grip, and remains impervious to moisture and temperature fluctuations.

The handles have been designed for optimal comfort, even during prolonged use. The ergonomic shape ensures a secure, non-slip grip, essential for controlling precise techniques (such as push-cutting).

Laser finish and colour variations: Personalise your kitchen

The 5CR15MoV steel blade features a technical finish achieved through laser engraving, echoing traditional patterns. Each blade undergoes rigorous heat treatment to achieve a stable hardness of 53–54 HRC, guaranteeing a uniform molecular structure and outstanding resistance to everyday mechanical stress. Each batch is subject to strict quality control to ensure flawlessly finished blades.

Laser engraving is a refinement technique we use exclusively on Tanaka knives.

We offer this set in five variations to match your kitchen aesthetic: Tierra del Fuego for mineral warmth, Ocean Blue for deep reflections, Sumi Black for pure understated style, Ivory for bright elegance, and Forest Wood for the authentic warmth of Pakkawood.

Care guide for a long-lasting edge

Cleaning and drying: The craftsman's golden rules

The dishwasher is a technical disaster for fine cutlery: aggressive chemicals and repeated thermal shocks alter the cutting edge structure, tarnish the blade finish, and eventually weaken the bolster joint. Hand washing in warm soapy water, followed immediately by drying with a soft cloth, remains the only method that extends the lifespan of your knife. Never use the abrasive side of a sponge, as it can scratch the steel surface and damage the laser finish.

Preserving the edge daily: Best practices

Proper care goes beyond cleaning; it also involves treating the blade with respect during use:

• Cutting surfaces: Cut exclusively on a wooden or soft plastic chopping board. Never cut directly in a frying pan, baking dish or on a marble surface, which would instantly roll the steel's edge.

• Technical tip: Never use the sharp edge of the blade to push or gather food on the board. This lateral friction is one of the main causes of premature dulling. Always use the spine of the blade for this.

Sharpening and longevity

• Daily care: Use a honing steel to realign the edge, or a manual sharpener for a quick touch-up.

• Periodic sharpening: Use a whetstone as soon as slicing loses its effortless feel.

Strict care following these guidelines significantly extends the lifespan of your tools and keeps their cutting edge sharp year after year.

The Kaitsuko Expert Verdict

The Chef Tanaka 7-piece knife set is the ultimate smart investment for cooks seeking straightforward efficiency. Where harder steels require strict cutting technique to avoid chipping, the Chef Tanaka range offers greater technical forgiveness.

This is a set we especially recommend to enthusiastic home cooks looking to equip themselves with a first complete set. The lightness of the blades reduces fatigue during long prep sessions, while the variety of blade profiles lets you tackle every cutting technique (push-cutting, rocking motion or trimming) with the right tool.

Accessories and add-ons: Optimise your culinary experience

To maintain the performance of your Tanaka set and ensure its longevity, we have selected accessories perfectly suited to 5CR15MoV steel:

• Honing steel (Wooden handle): The essential accessory for daily maintenance. It does not remove material, but realigns the blade's edge to maintain a crisp cut between sharpening sessions.

• Whetstone with handle: An ergonomic alternative for those new to the art of sharpening, making it easier to maintain a consistent angle.

• Knife carry bag: The technical solution to protect your blades from knocks and moisture when on the move or for safe storage out of reach.
