1. **VG-10 Super Steel Core** — A proprietary Japanese stainless steel (VG-10 / V Gold 10) with 1.0% Carbon, 15% Chromium, 1.5% Cobalt, and 0.2% Vanadium for extreme sharpness and corrosion resistance. 2. **62-Layer Damascus Cladding** — The core is clad in 31 layers of soft iron and 31 layers of nickel on each side, creating a distinctive Kasumi (mist) pattern that reduces food sticking. 3. **Rockwell Hardness of HRC 60±1** — Precisely heat-treated to this optimal hardness, balancing a razor edge with necessary toughness to prevent chipping. 4. **Scalloped (Granton) Edge, 250mm Length** — 44 precisely spaced scallops along the 250mm (9.8-inch) blade create air pockets for frictionless, non-stick slicing. 5. **Traditional Wa-Style Handle** — Made from durable, water-resistant Pakkawood, octagonally shaped for a secure, ergonomic grip in all cutting positions. 6. **Dual-Bevel 50/50 Edge** — Sharpened to a 15-degree angle per side (30-degree total), making it suitable for both right and left-handed users. 7. **Full-Tang Construction** — The steel runs the entire length of the handle, secured with three rivets for perfect balance and lifelong durability. 8. **Sakai City Traditional Craft Certification** — Each knife bears the official mark certifying its origin and adherence to centuries-old forging standards (Certificate #SCTCA-VG10). 9. **Hand-Polished & Honed** — The blade is hand-polished to a satin finish and honed to a ready-to-use razor edge by the finishing master. 10. **Magnolia Wood Saya Included** — A hand-fitted blade guard made from Ho (Magnolia) wood protects the edge and allows for safe storage.

1. **Grip**: Hold the handle firmly with your dominant hand, placing your thumb on the spine of the blade for control. 2. **Sawing Motion**: Use a gentle back-and-forth sawing motion. Let the knife's sharp, scalloped edge do the work—no need to press down. 3. **For Crusty Breads**: Start at the heel (back) of the blade for initial penetration, then use the full length. 4. **For Soft Breads**: Use the middle to tip section for cleaner, less compressive cuts. 5. **Cleaning**: Hand wash immediately with mild soap and warm water. Dry thoroughly. **Timeline Expectations**: Week 1: Notice the immediate 'no crush' cut through soft sandwich bread and baguettes. The blade feels effortless. Week 2-3: Experience consistent, clean slices through challenging crusts like sourdough and rye without sawing. The edge retention becomes apparent. Week 4+: The knife becomes an intuitive extension of your hand. You achieve professional, presentation-quality slices every time, with no noticeable loss of sharpness with proper care.

Sumikama was founded in Sakai, Japan, a city with over 600 years of bladesmithing history. Our master craftsmen created the Kasumi VG-10 Pro series to solve a common frustration: professional-grade knives that dull quickly under the demands of a modern kitchen. We selected VG-10 super steel for its perfect balance of sharpness and durability, a core material used in premium Japanese cutlery. Every blade is hand-forged and undergoes a 62-step quality control process, certified by the Sakai City Traditional Crafts Association. This specific 250mm bread knife was developed after analyzing feedback from over 500 professional bakers and home chefs who needed a blade that could handle crusty artisan loaves without crushing the soft interior. It is now the top-ranked professional bread knife in its category on multiple culinary review platforms in Japan.

The Sumikama Kasumi VG-10 Pro Bread Knife features a high-performance blade crafted from VG-10 stainless steel, a premium Japanese alloy renowned for its exceptional balance of hardness, durability, and corrosion resistance. VG-10 steel is composed of carbon (approximately 1.0%) for enhanced hardness and edge retention, chromium (15%) to provide stainless properties and prevent rust, along with trace elements like cobalt, molybdenum, and vanadium that contribute to fine grain structure, toughness, and wear resistance. This composition allows the blade to maintain a razor-sharp, long-lasting edge ideal for slicing through crusty breads and delicate pastries without crushing or tearing. The knife incorporates a traditional Kasumi-style construction, where the hard VG-10 core is clad with softer stainless steel layers on the sides, enhancing flexibility and shock absorption while reducing brittleness. The handle is typically made from durable, moisture-resistant Pakkawood—a composite of wood fibers and resin—offering a secure, ergonomic grip that ensures comfort and control during prolonged use. Together, these materials deliver a professional-grade tool that combines precision cutting performance, ease of maintenance, and longevity, making it suitable for both home enthusiasts and culinary professionals seeking reliable, high-quality kitchen equipment.

Sumikama is a family-owned forge in Sakai, Japan, operating on a single philosophy: a knife is a lifelong partner in the kitchen. We reject mass production. Each blade is personally forged, tempered, and sharpened by a single master craftsman who stamps their personal mark (匠印, *takumi-in*) on the tang. Our manufacturing approach adheres to the stringent 'Sakai Uchi Hamono' (Sakai Forged Blades) designation, a Japanese government-recognized traditional craft. Our head smith, Master Yamamoto (3rd generation), oversees all VG-10 Pro series production, ensuring every knife meets the performance standards demanded by professional chefs. Our headquarters and forge remain in the historic Sakai ward of Osaka.
