The industry's most unique sharpener and wrench combination. The unique design allows you to keep all* your broadheads razor sharp and will quickly become your "go to" tool. The wrench works with 2,3,4, and 5 blade broadheads. Simply run the blade through the two tungsten carbide blades and the ceramic honing rods 3 or 4 times each to precisely angle the shape of the cutting edge.
