The Gerber Dual Grit Sharpener is one of the most versatile sharpening stones you could ask for.  You can use it to not only sharpen axes, but also hatchets, knives, shovels, spades, machetes, and even lawn mower blades.  Plus, it can fit in your own pocket, so you can carry it with you wherever you go.  The shape and size of the Dual Grit are what earned it its rightful nickname: the Puck.

The contoured shape of the Dual Grit Sharpener makes it very easy to grasp as you sharpen the axe, but that same dual grit also means that it’s very effective at sharpening whatever tools you need sharpened.  Granted, as a typical axe sharpening stone, the Dual Grit Sharpener by GERBER cannot give your axe the fine edge it needs for maximum efficiency.
