NSF Certified Knives: What It Means and Who Needs Them
What does NSF certified mean for a knife? It means the knife has been certified to NSF/ANSI food equipment standards for sanitation, which commercial kitchens and health inspectors look for. Dalstrong's Gladiator Series 8" Chef's Knife ($79) is NSF certified for professional kitchen use, with a full-tang German X50CrMoV15 blade at 54–56 HRC. That makes it a good choice whether you cook in a restaurant or at home.
NSF International is an independent organization that writes public health standards and certifies products against them. Learn more at NSF food equipment standards.
What NSF certification looks at
- Materials that are safe for food contact.
- Design that's easy to clean, with no crevices where food and bacteria can collect.
- Durability so surfaces hold up to commercial cleaning.

Color-coded knives and cross-contamination
Many commercial kitchens color-code knives and boards by food: for example, red for raw meat, yellow for poultry, blue for fish and green for produce. It's a simple way to keep raw proteins away from ready-to-eat food. Dalstrong's Gladiator Series comes in color handles (ABS thermoplastic, per the product pages), including crimson red and white, which makes it easy to build a color-coded set. Check your own kitchen's or health department's color scheme, as conventions vary.
What NSF certification doesn't tell you
NSF certification is about sanitation, not sharpness or edge retention. Two NSF certified knives can perform very differently. For that, look at the steel and hardness: the Gladiator Series runs German X50CrMoV15 at 54–56 HRC with a 16–18° edge, a tough, easy-to-sharpen combination that suits busy kitchens.
Keeping NSF knives food safe
Certification covers design, not habits. Wash knives with hot, soapy water after each task, especially after raw meat, dry them right away, and store them clean. Hand wash rather than using the dishwasher; here's why.
