Popular among professionals, the Norton IM313 Tri-Stone has set the standard for sharpening for decades.
The Norton IM313 features three very large 11-1/2" x 2-1/2" oil stones in a convenient, easy-to-use system. These stones are long enough to handle any knife or tool thrown at them. The sharpening system holds the stones in a heavy-duty plastic base unit that mounts into an oil bath. The oil reservoir keeps the stones that are not being used submerged in the oil so they're ready to use. The system includes 16 ounces of quality Norton honing oil.
The Kit contains 3 oil stones. The first stone is the fast cutting coarse Crystolon stone. The second stone is the medium grit Crystolon stone, and the last is the fine India stone for final honing. This system is very popular among chefs and butchers.
The Norton IM313 is one of the most recognizable of all sharpeners. For many decades these sharpeners could be found in professional kitchens and butcher shops. Whether you call it the Norton IM313, the Norton 313, or just the Sharpening Workhorse, this sharpener has stood the test of time.
