This sharpener works! It is tapered to sharpen serrated edges. It will sharpen all edges - knives, tools, garden equiptment. It is easy to carry in a grunt bag, tackle box, pocket, anywhere. It has a fish hook groove. And as I said, it works! Most people want a second or a third one. The diamond is 600 grit. The sharpener is 4.5" closed and 7.5" open. The handle is also the sheath.
