Specialized Care & Maintenance

• Cleaning: Hand wash immediately after use with mild detergent. While technically dishwasher safe, we strictly recommend hand washing to preserve the 15° edge and prevent electrolytic damage in the dishwasher.
• Sharpening: Best maintained with a ceramic honing rod to keep the 15° alignment. For major edge resets, use 1000/6000 grit water stones.
• Storage: Store in a dedicated knife block or magnetic rack. Do not store loose in drawers, as the 55 HRC edge is susceptible to chipping if it strikes other metal utensils.

Safety & Handling for Professionals

• Ergonomic Benefit: The handle design is clinically proven to reduce pressure on the hand, making it ideal for users with early-stage arthritis or those performing 4+ hours of prep daily.
• Sanitation: The seamless construction between handle and bolster eliminates 'dirt traps,' ensuring the knife meets the highest HACCP standards for food safety.
