GreenPan titanium is smart cutlery made for serious home cooks. Our ultra-tough knives stay sharper longer. We take our blades up to 2000 Fahrenheit for hardening to create a durable and long lasting knife. Hand sharpened and coated with titanium for added durability, these knives deliver unparalleled performance and stand up to years of use. But we're also dedicated to making cooking better for everyone. We use steel and wheat straw to minimize our environmental impact with no compromise in performance. It's better for you, and better for everyone.
