Extra Thick for Extra Long Life
Those who do a lot of heavy sharpening know that the coarser stones wear faster than the finer ones. If you find yourself in frequent need of a coarse grit stone for restoring or repairing very dull or damaged edges, then the Nano-Hone Quad Stone will give you fast cutting 70 micron/200 grit and a long life. Made of 4 layers of the standard 70 micron/200 grit stone, the Quad stone is guaranteed to last.
Same Nano-Hone Quality
The Quad Stones are the same splash and go material as the standard Nano-Hone Water Stones, just four times as thick. Mounted to the same base, they work with the Nano-Hone Stone Stages, and are color coded with a red base just like their single thickness cousins.
