King Honing Grit Waterstone
This KING GOLD G-1 #8000 grit stone includes a 'Nagura' stone, a small stone intended to help maintain the main stone's surface, to take down high spots and raise sharpening slurry quickly.
These finer stone require less water prior to use due to their less porous nature, so a quick dip in some water should be sufficient.
King brand waterstones are one of the most popular brands of waterstone available today due largely to their predictability, familiarity and low price. Ask for a 'toishi' in Japan, and chances are you will be presented with a King stone.
