Chefknivestogo Black Felt Knife Guard 3pc Set. This combination fits the Tojiro 3pc set well. The guards used are the 3.5", 5.5", and 8.5". Please make sure to put the blade guards on the right way with the spine exposed and the edge covered. See photo #2. Important! Please dry your knives thoroughly before putting them into these guards. Otherwise, you may trap the water in the guard and it will rust your knives.
