GMP-Certified Manufacturing — Every knife is produced in a certified Japanese factory adhering to strict Good Manufacturing Practices for consistency.

Hand-Forged & Honed — Critical steps in the process are performed by skilled craftsmen, not fully automated machines.

Optimal Flexibility — The blade has a calculated flex perfect for boning, allowing it to bend slightly around bones without snapping.

Precision Weight: 4.2 oz (119g) — Engineered for control and reduced hand fatigue during detailed, repetitive tasks.

Rockwell Hardness: 60-61 HRC — A precise measure of the blade's hardness, ensuring it holds a sharp edge without being brittle.

1. Grip the Pakkawood handle firmly, placing your thumb and index finger on the blade's heel for control.

2. Use the narrow, flexible tip to navigate around joints and bones, making small, precise cuts.

3. Employ the central curved section for separating skin and meat from the bone in smooth strokes.

4. Clean immediately after use with warm water, mild soap, and a soft cloth. Dry thoroughly.

5. Store in the provided blade guard or on a magnetic strip. Never leave in a drawer unprotected.

Timeline Expectations:

- Week 1: Notice the immediate 'stickiness' reduction. The blade glides through connective tissue without tearing meat.

- Weeks 2-3: Experience consistent performance. No loss of sharpness despite daily use on multiple birds.

Tojiro was founded in 1953 in Niigata, Japan, the heart of samurai sword craftsmanship. Our master smiths created the DP Cobalt series to solve a common chef's problem: blades that dull too fast during long prep sessions, forcing constant sharpening that wastes time and ruins workflow. We chose a 13% cobalt alloy core because lab tests proved it resists wear 300% better than standard metals, laminated it with our patented VG-10 steel for stain resistance, and shaped it into a 150mm blade specifically for the intricate work of deboning poultry. Every knife is GMP Certified, forged in our Japanese factory where quality checks are done by hand. This focus on lasting performance has made it a top choice among professional chefs.

The Tojiro DP Cobalt 150mm Boning Knife is crafted from a high-performance cobalt alloy steel, specifically a VG10 core with cobalt alloy cladding, which forms its primary ingredient. This steel composition includes carbon for hardness and edge retention, chromium for corrosion resistance, and cobalt to enhance toughness and reduce brittleness, allowing the blade to maintain a sharp, precise edge even under the stress of deboning tasks. The handle is made from Pakkawood, a durable, laminated wood composite that is water-resistant and provides a secure, ergonomic grip, ensuring comfort and control during prolonged use. These ingredients collectively offer significant benefits: the cobalt alloy steel delivers exceptional sharpness and durability for clean, efficient cuts through poultry and other meats, while the Pakkawood handle enhances safety and reduces hand fatigue, making this knife a reliable tool for professional chefs and home cooks seeking precision and longevity in their kitchen equipment.
