The universal edge guard set by ergo chef includes 2 wide-blade and 3 narrow-blade guards to make a set of 5. The guards protect the edges of your knives - and your fingers, too! store and transport knives safely without damaging or dulling their blade edge. The bright colors help identify knives easily in a drawer or in a knife roll. The guards work on all stamped, forged, and ceramic knives. To clean, wipe with a clean, damp cloth. Set includes 5 different sizes and colors: 1 by 4.2-inch Pink (paring knife), 1 by 7.5-inch Red (Utility knife or santoku) , 1 by 8-inch orange (Carving or bread knife), 1.5 by 8-inch blue (chef knife), and 1.5 by 6-inch green (chef or santoku).
