The wrench works with 2, 3, 4, and 5 blade broad heads. 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. (Note: Some broad heads may need to be disassembled.). Features: Tungsten carbide sharpening blades Ceramic honing rods
