These blades are ice tempered and then precision flat ground for maximum cutting power. All the models in this series come with a razor sharp edge that lasts and lasts, and some have serrated edges uniquely appropriate to the tasks they were designed to do. The handles are carefully designed to ensure a strong, secure, yet comfortable grip. They feature a stiff Zytel core on the inside, with a softer, deeply checkered Kraton exterior for the kind of non-slip grip that must be felt to be appreciated.
