The microplastic-free nature of our knives is not accidental.
Did you know most high-end kitchen knives use "food grade" plastic handles, treated wood, or adhesives containing compounds that could mess with your gut biome and brain health? These create microplastics and release chemicals that are linked to real, long-term health risks—and they’re 100% in your kitchen right now.

At Kove Cutlery, we’re done with that BS. Our handles are made from surgical grade titanium, aerospace aluminum, and ceramic composites—durable, food-safe materials free of microplastics and toxic adhesives.
Ultimately, fewer contaminants in a product is always better.
