This pocket-sized sharpening stone, affectionately known by most of us as the Lansky Puck, is hands-down the best field sharpener for all of your axes, hatchets, machetes, shovels, spades, and even lawnmower blades. If it’s bigger than a knife, the Lansky Puck is your go-to for putting a razor-sharp edge back on it. The Puck is nothing more than a simple dual-grit round stone with a 120-grit coarse side and a 280-grit fine side, and a beveled edge for easy grip. It’s very affordable and reasonably lightweight, and fits easily into a pocket, pack, or toolbox. Keep one with you in the woods for touching up your axes and machetes, and another at the house for keeping a good edge on your garden tools.
