The newest and most advanced version of the classic Turnbox sharpeners that have been so popular for over 30 years. Featuring two 5-inch fine-grit diamond rods with steel cores, this is one of the fastest and easiest knife sharpeners to use. The hardwood base has two preset angles (20 and 25 degrees) to assure a precision edge on every knife from fillet and butcher knives to hunting and chef"s knives. The diamond sharpening rods store in the base when not in use and the base can easily be stored in a pocket, daypack, tacklebox, toolbox or kitchen drawer
