Lansky Deluxe 5 Stone System
works well on low end steel to create a bur, also worked pretty well on a cold steel lucky CPM-S35VN steel which i have always had troble sharpening, it took ages to sharpen a cold steel 4max scout aus10A steel but still did it eventually so can't complain you just really need a bit of patience to get a bur on hard steel, it does feel a bit cheap for the price could of been sturdier
