Smith's 50921 4" Dual Grit Combination Stone

Smith's Dual Grit Sharpening Stone is excellent for use on pocket knives, sport knives, tactical knives, or other cutting tools. The 100 grit side is for very aggressive removal of metal and the other, 240 grit, side is for less aggressive removal and can be used to sharpen somewhat dull blades for quick touching up. With a 4" length, this knife sharpener can easily fit into your pocket.
