Razor-Sharp 15-Degree Edge — Each side is sharpened to a precise 15-degree angle for a incredibly sharp and durable cutting edge.

Pakkawood Handle — Made from stabilized wood and resin for a secure, comfortable grip that is waterproof and hygienic.

Full Tang Construction — The steel of the blade runs the full length of the handle, providing perfect balance and durability.

Bolsterless Design — No bulky metal bolster at the handle, allowing you to use the entire blade length for sharpening and cutting.

GMP-Certified Manufacturing — Made in a certified Japanese factory that follows strict Good Manufacturing Practices for quality.

Hand-Finished — Each blade is hand-ground and polished by skilled craftsmen for a perfect final edge and finish.

1. Use on a soft cutting board like wood or plastic to protect the sharp edge. Avoid glass, stone, or ceramic boards.

2. Hand wash only with warm water and mild soap. Dry immediately with a towel. Do not put in the dishwasher.

3. Store in a knife block, on a magnetic strip, or with a blade guard. Do not toss loosely in a drawer.

4. Sharpen as needed using a whetstone (recommended) or a professional sharpening service.

Timeline Expectations:

- Week 1: Experience the 'out-of-the-box' sharpness. The knife will glide through ingredients with little pressure.

- Weeks 2-3: The edge remains noticeably sharp with daily use. You'll do less 'sawing' and more clean slicing.

- Week 4+: The superior cobalt alloy steel means the edge lasts. You may notice it's time for a light touch-up sharpening, but it will still perform far better than an ordinary knife.

Tojiro was founded in Niigata, Japan, a region famous for its bladesmiths. They created the DP series to solve a common kitchen problem: knives that dull too fast or are hard to sharpen. The answer was a patented 'cobalt alloy' steel core, a special metal blend that stays sharp much longer than regular steel. This core is protected by two layers of stainless steel, making it strong and rust-resistant. Every knife is hand-finished in a GMP-certified Japanese factory, ensuring perfect quality. This specific 240mm Gyuto model is consistently a top-rated choice for home cooks and professionals alike, praised for its balance and edge retention.

The Tojiro DP Cobalt Alloy Steel 240mm Gyuto Knife (model FU-809) is crafted from a sophisticated multi-layered construction that combines distinct materials to optimize performance and durability. The core of the blade is made of VG10 cobalt alloy steel, a high-carbon stainless steel renowned for its exceptional hardness, typically around 60-61 HRC, which provides superior edge retention and resistance to wear, allowing for precise, long-lasting sharpness ideal for professional and home kitchen tasks. This core is clad with multiple layers of softer stainless steel on both sides, a technique that enhances durability by protecting the hard core from chipping and corrosion while adding flexibility to reduce brittleness. The inclusion of cobalt in the alloy further refines the steel's microstructure, improving toughness and making it less prone to deformation under stress. The handle is constructed from Pakkawood, a laminated wood composite stabilized with resin, which offers a comfortable, ergonomic grip that is resistant to moisture, heat, and cracking, ensuring safety and control during extended use. Together, these ingredients—VG10 cobalt alloy steel for cutting precision, layered cladding for resilience, and Pakkawood for handling comfort—deliver a knife that excels in sharpness, longevity, and user-friendly design, making it a reliable tool for slicing, dicing, and chopping with minimal maintenance.
