Seki Magoroku Migaki

Seki Magoroku Migaki

Migaki (磨き) — The art of the polish

Migaki is Japanese for “polished” or “refined.” In the knife world it refers to a high-gloss blade finish — silky and shining, but not quite as reflective as a full mirror polish. In the Seki Magoroku Migaki series the name carries two layers of meaning: the literal high-gloss polish of the cutting edge, and the philosophy behind it — the continuous pursuit of perfection through repetition and mastery.

Master Line, second edition

The Migaki is the second edition of the Seki Magoroku Master Line — the absolute pinnacle of what KAI releases under this brand. Where the first edition (Kaname) drew its curved form from the torii arch of the Kamakura period, the Migaki takes inspiration from the katana. The characteristic curve of both blade and handle, the Damascus patterns that evoke rippling water, the clean hexagonal grip — everything references the aesthetics of the Japanese sword, yet fully placed at the service of the modern kitchen.

The series consists exclusively of the Gyūtō blade shape, available in three blade lengths. This is a deliberate choice: the Gyūtō is the most versatile kitchen knife in existence, and by offering a single blade type across three lengths KAI gives the user the freedom to work to measure without compromising the character of the series. The Migaki also introduces the Gyūtō shape for the first time to KAI’s European range.

The steel: VG Xeos core, 32 layers of Damascus

The Migaki blade features a VG Xeos steel core clad in 32 layers of Damascus steel. The softer outer layers envelop the hard core, absorb shocks, protect the cutting edge, and produce the characteristic visual pattern that makes every blade unique.

VG Xeos

VG Xeos is a premium alloy from Takefu Special Steel (武生特殊鋼材) — the same company that developed the renowned VG-10. It is produced via a special melting process that yields an extremely fine microstructure, resulting in measurably improved wear resistance, strength and hardenability compared to VG-10. Typical hardness: 61–62 HRC. The refined grain structure delivers longer-lasting edge retention under comparable use.

Damascus, 32 layers

Damascus steel is created by forge-welding and folding two or more different steels together. The 32 alternating layers produce the characteristic rippling pattern that evokes waves on a water surface — every blade is visually unique. After forging, the blade is chemically etched to emphasise the pattern contrast.

Migaki edge

The cutting edge itself receives an additional high-gloss polish — the migaki finish. This reduces drag during cutting, promotes clean food separation, and gives the blade its characteristic mirror-bright edge zone that distinguishes the cutting area from the Damascus-patterned body of the blade.

The blade type: Gyūtō

Gyūtō (牛刀) literally means “beef sword” — originally used for breaking down large cuts of beef. Today the Gyūtō is the Japanese equivalent of the Western chef’s knife: a knife for (almost) everything.

Compared to Western chef’s knives, the Gyūtō is ground thinner (typically 1.5–2 mm at the spine versus 2.5–3 mm for European knives), lighter in weight, and sharper in geometry — with an edge angle of around 12–15° per side instead of 20–22°. This enables a finer, cleaner cut, but calls for a little more care: harder steel is more brittle and sensitive to lateral forces.

Applications

• Meat & poultry — The pointed tip and slender blade allow precise work alongside bones. The length enables long, flowing cuts when carving. Suited for raw meat, cooked meat, carpaccio and sashimi.
• Fish & seafood — The thin geometry makes the Gyūtō highly suited to filleting, portioning, and precision-slicing fish. Fillets release cleanly without crushing or tearing.
• Vegetables & herbs — The flat section near the heel is ideal for push-cuts through hard vegetables. The belly towards the middle suits rocking motions when mincing herbs.

Cutting techniques

The Gyūtō supports all common cutting techniques: push-cut (straight down and slightly forward, for hard vegetables), pull-cut (drawing towards you for meat and fish), rock-chop (tip on the board, heel moving up and down for herbs) and tap-chop for fast, controlled chopping. The double-bevel blade is suitable for both right- and left-handers.

The handle: hexagonal pakkawood

The Migaki handle is hand-crafted from grey-marbled pakkawood with a hexagonal cross-section. Pakkawood is a composite material in which thin wood veneer is impregnated with resin under high pressure and temperature. It combines the warmth and aesthetics of wood with the moisture resistance and dimensional stability of a synthetic material.

• Hexagonal shape — Provides excellent grip and tactile orientation. The hand automatically feels the blade position without looking. Reduces hand and wrist fatigue during extended use.
• Moisture resistant — Virtually waterproof due to the resin impregnation. Does not shrink, swell or crack when exposed to moisture. Not dishwasher safe; always hand-wash and dry immediately.
• Handcrafted — Each handle is made by hand. The grey marbling varies slightly from knife to knife — evidence of artisanal production.

Heritage: 800 years of Seki

The name Seki Magoroku carries a history of almost eight centuries of swordsmiths’ craft. Seki, a city in present-day Gifu Prefecture, emerged as a swordsmithing centre during the Kamakura period (1185–1333). The legendary swordsmith Magoroku Kanemoto — also known as “Seki no Magoroku” (関孫六) — worked here during the late Muromachi period. His blades were prized by Oda Nobunaga and Toyotomi Hideyoshi. The principle his name represents — “does not bend, does not break, cuts well” — is the founding philosophy that KAI carried into its kitchen knife line when it was established in 1908.

With the Meiji era (1868) came a ban on carrying swords. Seki’s swordsmiths redirected their craft towards kitchen tools — and the city became the centre of Japanese kitchen knife production that it remains to this day. KAI was founded in 1908 by Saijiro Endo and grew into the world’s largest Japanese knife manufacturer.

Care

• ✅ Use a wooden or plastic cutting board. Stone, glass and ceramic will severely damage the edge.
• ✅ Hand-wash immediately after use. Dishwashers damage both the blade and handle material.
• ✅ Dry immediately after washing. Prolonged moisture can cause staining or oxidation, especially with acidic foods.
• ✅ Sharpen on a whetstone (1000–3000 grit for maintenance, 6000+ for finishing). Pull-through sharpeners and honing steels are not suitable for this steel.
• ✅ Store on a knife block or magnetic strip. Loose storage in a drawer damages the edge.
• ⚠️ Do not use for chopping bones, breaking cheese or as a lever. The thin, hard blade risks chipping or snapping under lateral force.
