1. **VG-10 Cobalt Super Steel Core** — HRC 60±1 hardness. A patented Japanese steel containing cobalt, molybdenum, and vanadium for exceptional edge retention and corrosion resistance. 2. **67-Layer Hand-Forged Damascus Cladding** — Each layer is meticulously folded and hammered, creating a flexible outer jacket that protects the hard core from chipping. 3. **Traditional Kasumi (Mist) Finish** — Applied by hand on rotating water stones, this finish indicates a high-quality convex grind for superior food release. 4. **Kengata (Sword-Shaped) Gyuto Profile** — A 240mm (9.4-inch) blade with a flatter belly for precise push-cutting and a pointed tip for detailed work. 5. **Right-Handed D-Shape Pakkawood Handle** — Ergonomically contoured from stabilized wood and resin for a non-slip, comfortable grip that reduces fatigue. 6. **Seki City Origin & Designation** — Manufactured in the historic blade-making city, carrying its official traditional craft designation. 7. **Razor-Sharp 15-18 Degree Edge Angle** — Hand-finished to a much finer angle than typical European knives (20+ degrees) for drastically easier cutting. 8. **Full Tang Construction** — The steel core runs the entire length of the handle, providing perfect balance and durability. 9. **Magnolia Wood Saya Included** — A traditional Japanese blade guard made from moisture-resistant magnolia wood for safe storage. 10. **GMP-Certified Workshop** — Every knife is produced in a facility adhering to strict Good Manufacturing Practice standards for quality control. 11. **Individual Sharpening & Inspection** — Each knife is hand-sharpened and inspected by a master sharpener before shipment, with a certificate of completion.

1. **First Use:** Hand wash with mild soap and warm water. Dry immediately with a soft cloth. Apply a light coat of food-safe mineral oil to the blade and handle. 2. **Daily Care:** Always hand wash and dry immediately. Never put it in the dishwasher, as the heat and chemicals will damage the steel and handle. 3. **Cutting Surface:** Use soft wood, plastic, or composite boards only. Glass, stone, and hard bamboo boards will dull the edge quickly. 4. **Storage:** Always use the provided saya or a magnetic knife strip. Never toss it loosely in a drawer where the edge can get nicked. 5. **Sharpening:** Use a whetstone (1000/6000 grit recommended) every 3-6 months with light, consistent pressure. Follow our guide or consult a professional. **Timeline Expectations:** *Week 1:* Notice the immediate 'glide-through' feel on tomatoes, onions, and herbs. The knife feels balanced and secure. *Week 2-3:* You develop muscle memory for the blade's precision. Prepping time decreases as you rely on its consistent sharpness. *Week 4+:* The knife becomes an extension of your hand. You experience less hand fatigue, enjoy cooking more, and maintain the edge with simple, periodic honing.

Sumikama was founded in Seki City, Japan, a region designated by the Japanese government for over 700 years as the home of sword and blade craftsmanship. The Kasumi VG-10 Pro was created for home cooks who felt let down by dull, generic knives that made prep work a chore. Our master smiths selected VG-10, a patented cobalt steel, for its perfect balance of sharpness and durability, cladding it in hand-forged 67-layer Damascus for resilience. Every knife is individually sharpened and inspected in our GMP-certified workshop, earning the Seki City traditional craft designation. It's now a top-ranked chef's knife in its category, consistently praised in user reviews for its 'laser-like sharpness' and 'effortless cutting'.

The Sumikama Kasumi VG-10 Pro Kengata Gyuto 240mm Japanese Chef Knife is crafted from high-quality materials designed for exceptional performance and durability. The core of the blade is made from VG-10 stainless steel, a premium Japanese steel known for its high carbon content (approximately 1.0%) and cobalt addition, which provides superior hardness (around 60-61 HRC), excellent edge retention, and resistance to corrosion, ensuring the knife maintains sharpness through prolonged use. This core is clad in softer stainless steel layers, typically 13- or 15-layer Damascus cladding, which not only enhances the blade's aesthetic with a distinctive wavy pattern but also adds toughness and flexibility, reducing brittleness and making the knife more resistant to chipping during rigorous cutting tasks. The handle is constructed from Pakkawood, a composite material made from wood fibers and resin, offering a durable, moisture-resistant grip that combines the natural feel of wood with enhanced stability and hygiene, preventing warping or cracking. Additionally, the knife features a full tang design, where the blade steel extends through the handle, providing optimal balance, control, and strength for precise cutting. These ingredients collectively deliver a professional-grade tool that excels in sharpness, longevity, and user comfort, ideal for chefs seeking precision and reliability in kitchen tasks.
